Our top-rated mattresses have been personally reviewed and highly rated. Many couples start with a queen size mattress. In fact, queens are some of the most popular beds on the market. But over time, a queen size can begin to feel confining. Maybe your children like to climb into bed with you on Saturday mornings, or your partner tends to toss and turn more frequently. When you both start to feel cramped, it may be time to upgrade to a California king size mattress.Once you’re ready to upgrade, you will need to decide between a standard king and a California king. Both sizes are suitable for most couples—even with your children snuggled in the middle. When compared to a standard king, a California king has 4 more vertical inches, but is 4 inches shorter horizontally. But, depending on your height, sleep position, and the size of your bedroom, a California king mattress may be the best option for you.This article will cover the pros and cons of a larger California king mattress, and introduce you to some of the best California king beds on the market.Best California King Mattress Summary Best California King Mattress Overall: Amerisleep AS3 Best California King Mattress for Cooling: Zoma Boost Best California King Mattress on a budget: Vaya Mattress Best California King Size Innerspring: Saatva Classic Best Flippable California King Mattress: Nolah Signature 12 Best California King Size Memory Foam Mattress: Zoma Start Best California King Mattress for Athletes: Bear Pro Best California King Mattress for Athletes: Helix Midnight Luxe Best California King Mattress Luxury Model: Purple® Hybrid Premier Best California King Mattress Overall: Amerisleep AS3 Your browser does not support HTML5 video.

Claim Deal Your body type and sleep habits determine the mattress firmness you find most comfortable. At Amerisleep, they understand this and have created a line of 5 different memory foam mattresses and 3 hybrid mattresses to accommodate every comfort need.The AS3 comes with a 100-night sleep trial that allows you to test out the mattress. Amerisleep wants you to be happy with your new bed and will provide a full refund if the mattress is not right for you. Each Amerisleep mattress also comes with a 20-year warranty to cover any manufacturing defects.How Lying Down FeelsOur favorite Amerisleep mattress is the AS3 because it has a medium comfort level—making it ideal for most sleep positions.The AS3 offers just the right amount of support and cushioning for most sleepers. Many have commented on its ability to relieve pressure points and provide a balanced sleeping surface, making it ideal for those who suffer from back or joint pain. The mattress also offers good motion isolation, meaning that movements from a sleeping partner are minimized.People who bought the Amerisleep AS3 California king rave about it (with one exception we noted here). Here are some of their comments:PK: I was glad to be able to order a California king and receive it in a timely fashion. It has been very comfortable.Natalie: We ordered a California king. It is too long and not wide enough. I struggle daily with making the bed because it is sleigh bed style so there’s no room for sheets or comforter. I struggle weekly with changing sheets because I have to wrestle with mattress to get fitted sheet on. Sky Pilot: Bought new California king mattress to replace a Sleep Number bed. We have had 2 Sleep Number beds in 25yrs and this beats Sleep Number hands down. Was worried not being able to adjust the firmness would be a factor but turns out didn’t have to worry. Perfect support every night.Inside the MattressThe cover of the AS3 features a lightweight fabric—designed to improve airflow and heat retention. This cover is also removable and machine washable, so it is easy to keep your California king mattress clean.Beneath this cover, the AS3 features Bio-Pur® foam, a plant-based memory foam that is healthier and more comfortable than traditional memory foam. To make this layer, Amerisleep replaces a portion of the petroleum-based oils with plant-based oil—creating a foam that is safer for you and the planet. Plus, this foam has more breathability and responsiveness than poly-foam or traditional foam.Beneath this layer is Amerisleep’s Affinity with HIVE® transition layer, zoned to provide a balance of comfort and support. Around the neck and back, HIVE® delivers more stability, but near the hips and shoulders, it allows for more compression and cushioning. HIVE® also prevents excessive sinking, so your spine stays aligned no matter what sleep position you take.Supporting both the Bio-Pur® and HIVE® layers is Amerisleep support foam, Bio-Core®. This base ensures the California king mattress keeps its shape and does not develop sagging or indentations.SEE ALSO: Best King Size MattressPros Sturdy base foam extends the mattress's expected lifespan Targeted cushion for shoulders and hips, with reactive back support Comfy and pressure-relieving plant-based memory foamCons Largely composed of synthetic materials What the testers say: “I would rate the AS3 around a 6 on the 10 point firmness scale. Lying down, I experienced noticeable contouring and cushioning comfort while still feeling properly supported. The foams adapted to my body shape for pressure relief while keeping my spine on an even plane. Changing positions and getting in/out of bed was easy thanks to the responsive materials.” – Dr. Colleen Ehrnstrom, Ph.D., AS3 Reviewer Read Our Full Review of the Amerisleep AS3 Mattress Best California King Mattress With Memory Foam: Zoma Boost Your browser does not support HTML5 video.

Enjoy restful sleep without worrying about overheating with this cutting-edge cool technology.Like other Zoma mattresses, the Zoma Boost comes with a 100-night trial and a 10-year warranty.How Lying Down FeelsThe Zoma Boost California king mattress is designed to offer a medium to medium-soft feel, which is typically preferred by side sleepers. The mattress has a comfortable and supportive feel, providing a good balance between firmness and softness.Sleepers can expect to sink slightly into the mattress’s top layer of quilted foam, which conforms to their body’s shape, providing pressure relief and reducing motion transfer.The infused memory foam in the Zoma Boost ensures that heat is drawn away from your body while you sleep, allowing you to remain cool and comfortable all night long. It also provides superior pressure relief, helping to reduce any aching or soreness associated with poor posture or sleeping on an uneven surface.Reviews are limited on the Zoma Boost as it is a newer mattress, but here is what some of the first respondents have said:Cheryl M: My husband snored and I couldn’t sleep. First night he didn’t snore. And he hasn’t ever since. It’s been now about 3 years And last summer I fell hurt some ribs. Thank goodness for the bed at that time tooDalton C: I am so happy with my Zoma Boost bed! Since I received it, I have had the best nights sleep. It is extremely comfortable and keeps me cool. Highly recommend!Michael T: My wife and I received our Zoma boost over the weekend. It provides us with a level of support and comfort our previous mattress didn’t. It is so stable that I didn’t feel when my wife climbed out of bed for work.Inside the MattressThe California king mattress’s advanced cooling cover is made of a breathable, stretchy fabric that promotes airflow and helps to keep sleepers cool and comfortable throughout the night. It’s swift to greet sleepers with a pleasantly icy feel, like a gentle cloud embracing the body. Quilted into this cover fabric is hypersoft foam for a pillowy feel.The mattress’s primary comfort layer is made of graphite-infused memory foam, which provides pressure relief and reduces motion transfer. The gel infusion helps to regulate temperature and prevent heat buildup, making it ideal for sleepers who tend to sleep hot.The next layer of the California king mattress is made of Reactiv™, a latex-like foam that provides support and bounce. This transition layer helps to prevent sinkage and promotes proper spinal alignment.The mattress’s bottom layer is made of pocketed coils, providing a stable foundation for the mattress and helping to prevent sagging.Pros Airy pocketed coils offer motion isolation and edge support Designed to promote coolness and breathability, thanks to its graphite-infused memory foam layer and breathable cover Transition foam ensures surface responsivenessCons Mattress is only available in one firmness level & may not be suitable for all sleeping positions and preferences What the testers say: “The responsive Reactiv™ foam layer and pocketed coils worked together to provide a nice balance of contouring without causing me to feel stuck. I could change positions and get in and out of bed with ease, rating it a 5 out of 5 for ease of movement.Motion isolation also earned a perfect score of 5 out of 5.

It’s also bouncy and responsive without containing any steel springs.While a tiny minority mentioned problems with ordering and delivery, the vast majority are happy with ordering online:Jack C: Very soft and comfortable, but still a lot of support. I tried multiple online mattress stores, and I returned all the California king mattresses except this one, it is so comfortable.Maxine: I ordered it extra early so the latest estimated delivery was a week before I would need it for my new apartment. However, the mattress came about three weeks after the latest delivery estimate. Customer service was really nice but didn’t seem to have access to accurate delivery estimates either.Tia W: My husband and I are extremely impressed with this mattress. First of all, the ordering and delivery process was a dream. I appreciated that the customer service representatives called us with updates and to see if we had questions about delivery. Set up of the mattress was also very easy! Sleeping on it has been life-changing.Inside the MattressThe Vaya Mattress contains two layers—a soft comfort foam layer and a supportive, durable base. The comfort layer features a plush, hypoallergenic memory foam that hugs the body for pressure-free support. Unlike traditional memory foam, Vaya foam has a slight bounce, so you never feel stuck or experience excessive sinking with this California king mattress. Plus, Vaya foam is also more breathable than most memory foams, and the soft, lightweight cover helps improve airflow around the surface of the bed.Beneath this layer is a high-density foam that maintains the shape and structure of the mattress and prevents sinking.

Claim Deal The Saatva Classic is a welcome twist on the traditional innerspring mattress design. The bed relies on an open coil base like the standard innerspring mattress, and the Classic also has a Euro pillow top like many upscale spring mattresses.However, unlike the typical innerspring mattress, the Saatva Classic has an extra layer of pocketed coils, a strengthened middle for lumbar support, and reinforced sides for edge support. It’s also backed by a 365-night sleep trial and a lifetime warranty.How Lying Down FeelsWith three firmnesses available, the California king mattress can feel quite hard and supportive or plush like a cloud. The pillow top cushions the body regardless of the bed’s firmness, with sleepers gently sinking into the surface.The middle of the Saatva Classic also feels quite supportive in every firmness, thanks to the brand’s reinforced back support.While there are very few people who are dissatisfied with the Saatva mattress, some noted some dissatisfaction:L: I ordered LUXURY Firm Cal king and am very satisfied with it. The quality was not up to par with the old mattress that it replaced that cost twice as much but the difference in feel when you lay on it is I say way better than our old mattress. We were not expecting our mattress to arrive early so I was surprised.Paulette B: This is an update on my thoughts about this mattress. I bought a Cal king just about a year ago. The mattress is very heavy so if you need new flooring do it now. However, you won’t be sorry you bought a Satvaa. It’s not too hard nor is it too firm. It hits the sweet spot. The adjustable mechanism is smoothRead more about review stating Can’t wait to get in bed!, not noisy like a few others I tested.Jroeger: It’s been a month since our luxury firm Cal king was delivered. My wife and I both think it’s a great product and are enjoying better, longer sleep. The mattress is 14.5 inches and fits perfectly on our existing bed frame. The workmanship is first rate and looks high quality.Inside the MattressThe top of the mattress is a 3-inch thick pillow top with Lumbar Zone® Quilting. The cover fabric is organic cotton fabric, a material that keeps moisture and heat moving away from the body. Saatva has treated this fabric with a botanical compound designed to keep microbes from settling inside the mattress.Underneath the thick pillow top is a memory foam layer with Lumbar Zone® Active Spinal Wire, designed to keep the spine in neutral alignment. The memory foam is also certified by CertiPUR-US®, meaning a third-party organization has reviewed the production and found the foam free of potentially harmful materials.The middle layer is pocketed coils, zoned to boost back support under the torso. The responsiveness of these individually wrapped coils let the bed contour to the body and lower tension.The base of the Saatva Classic is hundreds of tempered steel coils, with plenty of room for air to circulate between these coils. Ringing these coils are dense foam rails that increase the side’s stability, providing reinforced edge support.Saatva also notes that the two-coil design is meant to deter sagging, which can create discomfort and cause morning aches.Pros Saatva will set up a delivery appointment for the mattress Pillow top stays cool and smells fresh as it cushions sleepers Targeted back support ensures pain-free morningsCons Return fee charged on any Saatva mattress Best Flippable California King Mattress: Nolah Signature 12 Price: $1099 to $2398Mattress Type: Memory FoamMattress Height: 12 inchesFirmness: Medium-Soft (4 on the firmness scale)Best for side sleepers seeking a memory foam mattressAvailable in twin, twin XL, full (double), queen, king, California king, split king Warranty Lifetime Sleep Trial 120 Nights Shipping FreeRecommended ForSide sleepersPetite sleepersHot sleepers of varying stylesMattress HighlightsDurable support core for high-value constructionTransition counters the plush comfort foamCooling AirFoam™ for cushioningSave Up to $900 on the Nolah Signature 12 with our discount code.

It boasts multiple cooling technologies like AirFoam™ and a cooling cotton cover to both draw heat away from you and keep the cool air flowing all at once.Most people who bought the Nolah Signature looking for neck pain relief, but a minority of sleepers say it can be better:Rachel C: Helped neck pain. At my age, anything that helps is good. My hubby likes his Nolah mattress, so I finally got one. I rated it a 4 because I thought the purchase should have included a washable cover. I bought one from another seller, but took it off after 2 nights. It made the mattress less soft, so I couldn’t sleep on my side.Ellen: Nolah is comfortable and the shopping experiences was smooth and easy. I do sleep longer but I still wake up with some neck and low back pain. However, I still like the mattress and its 100% better then my tempur-pedic that I’ve had for many years.Harvey M: The Nolah Signature 12 is extremely comfortable.

While it’s design is budget-friendly, the Start doesn’t skimp on offering supportive comfort.While only a few mention the California king many have purchased king beds from Zoma and been happy with them:David L: Zoma Cali king makes me feel like one. After trying many cheap coil/foam hybrids and falling thru to the bottom I got the Zoma start and have abandoned all the others mattresses that I ended up buying foam toppers and covers for.Scott V: I purchased a king size mattress about 4 months ago and loved it. We just ordered our second oneMagnolia P: My partner has a Zoma and my first time sleeping on it I had to know what it was. I’m a very hot sleeper and it’s so cooling and not too hard or too plush. I bought the king size and and split the payment into 4 and it was so affordable for me. Very happy with the purchase.Inside the MattressThe Zoma Start features a 1-inch layer of gel foam to help wick away body heat, a 1-inch layer of Reactiv® material that offers adaptive support, and 8 inches of Support+® foam to firm up the mattress’s feel and help prevent sagging and soft spots. These foam layers are all wrapped up in a breathable AirCloth cover fabric.Aside from staying cool at night, the durable materials inside the Zoma Start establish long-lasting motion isolation. The memory foam swallows movement at the point of impact, so if you shift positions in the night your partner sharing the bed won’t feel a thing.The Zoma Start is also one of the top mattresses without fiberglass, a material that’s traditionally used to establish a flame-resistant bed. Fire safety is important, of course, but fiberglass has the drawback of causing skin irritation and breathing troubles if it escapes the mattress. Because of this, Zoma and many other manufacturers are moving to non-chemical alternatives for consumer safety.Pros Temperature-neutral gel foam and airy cover fabric Responsive transition foam enables easy movements Support foam for a healthy spine alignmentCons Simple thin mattress design means only a few special features What the testers say: “Another point that swayed me in the Zoma Start’s favor is that it’s a well-known mattress without fiberglass. Some of the consumer reviews I browsed before testing it expressed the same as me, saying they had been looking for a budget-friendly mattress made without this troublesome material.” – Dr. Nilong Vyas MD, MPH, Zoma Start Reviewer Read Our Full Review of the Zoma Start Mattress Best California King Size Mattress for Athletes: Bear Pro Price: $895 to $1495Mattress Type: Memory FoamMattress Height: 12 InchesFirmness: Medium-firm (6.5 on the firmness scale)Best for back sleepers who sleep hotAvailable in twin, twin XL, full (double), queen, king, California king Warranty 10 Years Sleep Trial 100 Nights Shipping FreeRecommended ForBack sleepersHot sleepersAthletes and physically active peopleMattress HighlightsCelliant® fabric transforms body heat into infrared energyCopper-infused foam promotes clean, cool comfortGel memory foam eases pressure points for swift recoverySave Free Shipping on the Bear Pro with our discount code.

And if you plan on sharing your king size bed, reviewers also noted how they never noticed their partners shifting place in bed.People who have purchased the king and California king are mostly happy with their purchase. One even preferred the Pro Cali king over the Original:Joanna N: Bear mattresses are the most comfortable mattress I have ever slept on. I have a bad back and since buying my first Bear I wake up in less pain. I would highly recommend the Hybrid it’s the perfect balance between memory foam and coil.Robert J: Too soft for me & my family.

With this Queen purchase I am currently pregnant, so there are some discomforts that I am experiencing due to this. Currently, using a mattress topper to soften the bed and lessen my hip pain.Inside the MattressAt 12 inches high, this mattress has four layers—a copper-infused memory foam, gel-infused memory foam, a responsive layer, and a high-density foam support base. The copper infusion in the top layer improves the breathability of this layer. Since copper is a natural heat conductor, body heat is able to pass through this layer quickly. Copper is also naturally anti-fungal and antibacterial—creating a cleaner sleep surface.The gel foam in the second layer helps with cooling by absorbing heat, while the responsive layer prevents sinking and ensures that you stay lifted on the mattress.

Depending on which cover you choose, you can enjoy cooling breathability or thermoconductivity that keeps you cool all night long.Reviews are limited on the Helix Midnight Luxe Cali kings, but the feedback we have from the website is mixed:Nathan D: Setup was easy but overall I am not impressed. It doesn’t seem to be good for side sleeping. The “cooling” topper is not effective and isn’t worth the money as an add-on. I am 6’6″ and about 250lbs. The bed is a Cali king. I think you could achieve the same results for less money elsewhere.Stephen S: My Helix Midnight Luxe, Cali king, was shipped within 3 days of ordering and arrived 3 days later. The entire experience was smooth. Oh, the mattress? 5/5 so far! My sleep hasn’t been so comfortable in years!James M: Incredibly happy with this purchase! Got the Cali king bed with adjustable base. Super easy to set up and had great sleep on the first night.Inside the MattressThe Midnight Luxe starts off with the optional cover. You have a choice between highly breathable TENCELTM fabric or highly thermoconductive GlacioTex fabric that can pull heat away from your body.Whichever cover you choose, it will wrap around the cooling premium pillow top. This top offers extra comfort and pressure relief to cushion you without letting you sink into the bed. The buoyancy of the pillow top is enhanced by the high-density Memory Plus Foam comfort layer that relieves pressure while keeping you lifted.Underneath the comfort layer and pillow top, you’ll find a transition layer of gel visco to increase the responsiveness and cooling power of the mattress. Another transition layer of high-grade polyfoam allows for seamless progression to the coil layer.Next, the support core is made of over 1,000 individually wrapped coils that offer more support to the middle of your body and around the perimeter. This ensures you get extra lift where you need it and there’s even support throughout the entire sleep surface.The coil support core sits on top of a DuraDense Foam layer that provides stability, motion isolation, and durability to the entire mattress.

The Purple Hybrid Premier 3 officially has a medium-soft feel, cushioning the body for weightless comfort without being too plush. Meanwhile, the Purple Hybrid Premier 4 has a rating of soft, designed to cradle the most curvaceous of sleepers and overall mimic a personal cloud.Reviews are mixed on the Purple California king. More than one person noted the mattress size was not the proper size:Angela H: I bought a queen mattress over two years ago but needed a bigger mattress so I just bought it in California king. It took about a week or two for my back to realign to a healthier position but after that, I’ve had the best sleep ever!Jaimieleigh R: I bought the the 3″ Cali king, it is pretty comfortable but definitely not work the money I’ll be paying for it.

No matter your body type, this grid will hug each curve of the body and ensure a weightless sleep. When purchasing this mattress, you have the option of selecting either 3 or 4 inches of the Purple Grid™. 4 inches is an excellent option for heavy sleepers and back sleepers since it will provide more responsiveness and cushioning.Beneath the Purple Grid™ is a thin layer of poly-foam and a base of individually wrapped spring coils.

A standard king measures 80 inches by 76 inches, while a California king measures 84 inches by 72 inches—giving the standard king more width (4 inches) and the California king mattress more length (4 inches).

To help you understand the difference between each mattress size and how it compares to a Cal king, we have included an overview below.Mattress SizeDimensionsKing Size (Eastern King)76 inches by 80 inchesCalifornia King Size (Western King)72 inches by 84 inchesSplit-King (2 Twin XLs)76 inches by 80 inchesWyoming King84 inches by 84 inchesTexas King (Grand King)80 inches by 98 inchesAlaskan King108 inches by 108 inchesIs a California King Right For You?You know a California king mattress is 84 inches by 72 inches, but what does that mean in terms of your sleep experience? We provide more clarity on these questions below.Body TypeThe best California king bed is ideal for those 6 feet tall and up. The extra length of this size establishes a mattress for taller people that gives more legroom and prevents feet from dangling off the end of the bed.Most couples typically find a Cal king bed comfortable and spacious. With 72 inches of width, these beds provide plenty of room for couples to spread out or for children to climb into bed with you.Larger couples who need more upper body room, or couples who just prefer more separation, may prefer a standard king size bed since it does offer 4 more inches of width than the Cal king.Bedroom SizeThe standard U.S. bedroom is 11 inches by 12 inches—this size room is not suited for a king mattress or a California king mattress because it doesn’t leave enough room to walk comfortably around the bed.At least 2 feet of space should be available on all 3 sides of the bed to make movement in the room comfortable. Therefore, master bedrooms are much more suited to a king or Cal king.Master bedrooms measure 14 inches by 16 inches and will need a bed large enough to fill out the room comfortably. Plus, you will have plenty of room to maneuver around the bed in a master suite.However, not all bedrooms will have these standard dimensions. In those cases, it is best to measure for yourself and decide which mattress size will be the best fit. If the room is more narrow—a Cal king will likely work best. If the room is wider—you may want to opt for a standard king size bed.Advantages and Disadvantages of a California King MattressA California king mattress comes with several benefits.These mattresses….Fit well into larger bedroomsOffer taller sleepers more legroomAllow couples to spread outCreate a more luxurious sleep experienceHowever, they do have a few drawbacks.With a California king…It may be harder to find accessories—such as bed frames, sheets, and beddingAccessories may be more expensive than those for a standard kingMoving the mattress may be difficult since it’s heavy and may not fit through all doorwaysStandard size bedrooms may be too small for the mattress to fit comfortablyOther Things to ConsiderAs you can see from the mattresses outlined in this article, California king beds feature several different firmness levels, layers, and materials. To help you make the most informed choice possible, we’ve broken down the most common variations.Firmness Options and Sleeping PositionsYour mattress should feel comfortable and support your body type and sleep position. A soft mattress may be ideal for side sleepers, while stomach sleepers may prefer an extra firm mattress to prevent sinkage and maintain proper spinal alignment. Ultimately, finding the right balance between comfort and support is crucial for a good night’s sleep.When shopping for the best mattress, you will notice most beds have a firmness ranking from 1 to 10—1 being the softest and 10 being the firmest. We have included a quick overview of the firmness scale below.1 to 2 (Soft): This firmness is suitable for side sleepers and lightweight sleepers who need more cushioning around the hips and shoulders. Lightweight sleepers will not find adequate contouring with a firmer mattress because they will not sink enough, but a soft mattress is ideal for lighter sleepers.3 to 4 (Medium-soft): These beds are also excellent for lightweight sleepers and side sleepers. With a bit more firmness, side sleepers will experience contouring and support without excessive sinking.5 (Medium): Medium mattresses are a great option for most sleep positions—including side sleepers, back sleepers, and combination sleepers. A medium mattress cradles the curves of the body no matter what position you take. Plus, it is responsive enough to prevent sinking for both side and back sleepers. These beds also work well for couples with different sleep positions.6 to 7 (Medium-firm): A medium-firm mattress works well for back and stomach sleepers since it will cushion joints but also prevent sinking and spinal misalignment. If you’re looking for the best mattress for back pain, choose a medium-firm bed. These mattresses also prevent heavier sleepers from feeling “stuck” in the bed or from sinking too far.8 to 10 (Firm): This firmness is a good choice for back and stomach sleepers, as well as heavy sleepers. These mattresses keep the chest lifted when stomach sleeping—alleviating strain on the neck and back. It also keeps the hips lifted when back sleeping—ensuring a neutral spine.Mattress Layers and TypesYou may be wondering—what is a mattress type? The materials that make up the various layers of a mattress determine its type. The kind of bed you select will affect the support and overall comfort you experience.Here are 4 of the most common mattress types:Memory Foam MattressesMemory foam mattresses provide superior comfort and contouring to help you experience a weightless sleep. Unlike most mattress materials, this foam offers pressure relief and support—allowing your aching muscles adequate time to repair. Memory foam beds can help all sleepers find a more comfortable nighttime position, but those who suffer from back pain can find tremendous relief with these beds.However, not all memory foam is created equal. Traditional memory foam tends to be very soft—causing sleepers to sink and throw their spine out of alignment. Most memory foams may also trap body heat—causing sleepers to wake up during the night due to overheating.When shopping for a memory foam bed, it is best to opt for a plant-based foam. This type of foam is non-toxic and safer for you to rest on. Plus, it is more breathable and more responsive than most memory foams.Latex Foam MattressesLatex foam has a comfort level similar to memory foam. But the elasticity of latex creates a mattress with slightly more bounce. Although this foam doesn’t provide the deep compression that memory foam does, those who like to feel more lifted on the mattress may prefer a latex bed.Latex foam is also natural and eco-friendly—creating a clean and non-toxic sleep surface. Plus, latex is naturally resistant to bacteria, viruses, and dust mites, so they are ideal for those with allergies, asthma, or nighttime congestion.Hybrid MattressesFor those looking for a mattress with the contouring of memory foam but the bounce of an innerspring bed, a hybrid mattress may be the best option. These beds have 2 to 3 inches of foam—either memory or latex foam—in the comfort layer. But the base layer of a hybrid mattress features wrapped steel coils. In many mattresses, these coil systems will be balanced—softer near the hips and shoulders, but firmer near the neck and back.Innerspring MattressesInnerspring mattresses feature a support base of steel spring coils, similar to a hybrid. However, innerspring mattresses don’t have a thick layer of foam on top. Most of these beds have a top layer made of cotton or wool. Although some spring coil beds may feature foam, the foam layer is usually thinner and not thick enough to protect sleepers from pressure points.Innerspring beds are popular in the U.S., primarily because they are so affordable. But these beds do not provide the same amount of contouring as memory foam or latex foam. Plus, it is easier for dust and dirt to become trapped inside the spring coil system—causing them to break down quickly and create breathing problems for sleepers.PriceIf you are looking for huge but budget mattresses, shopping for a California king size bed may be a smart choice. Most California king size mattresses are priced the same as standard king-size mattresses—these beds cost anywhere from $850 to $3,000.However, because king size mattresses are more popular, accessories for these beds tend to be less expensive than Cal king accessories. If you are considering a California king, be sure to price bed frames, sheets, mattress protectors, and comforters to be sure they fit well within your budget.You can also save on California king size beds and accessories by shopping online mattresses. Web-based mattress brands offer their beds at lower prices because they have fewer overhead costs.Warranty and Sleep TrialIt may take around 2 to 3 weeks to become accustomed to a new mattress. But when shopping inside a mattress store, you only have a few minutes to test out a bed—this is not enough time to be sure it’s right for you.To allow you more time to try out the mattress, many mattress in a box brands offer a sleep trial period that enables you to test out the mattress at home. Most sleep trials last between 30 and 90 days.Because defects do happen, a good mattress warranty is essential. Most companies offer a warranty of at least 10-years. Anything longer than this will likely be prorated—this means customers will be responsible for paying a portion of the repairs or replacement costs if something goes wrong with the mattress after the first 10 years.When considering a warranty, it is helpful to keep in mind that warranty length does not always reflect the life of the mattress. Most innerspring mattresses last only 5 to 6 years, while hybrid beds, and memory foam and latex foam mattresses will last between 10 and 12 years.Choosing the Right Mattress SizeMattress SizeDimensionsTwin38″ x 75″Twin XL38″ x 80″Full54″ x 75″Queen60″ x 80″King76″ x 80″California King72″ x 84″FAQsWhat is the best California king mattress?Everybody has different sleep needs, so it’s hard to say what the “best” California king mattress is. When choosing a comfy bed, consider your sleep style, body type, and preference for firmness.With that, though, many sleepers love medium memory foam mattresses because they’re comfortable for the majority of sleepers.How much does a California king mattress cost?The price of a California king mattress ranges depending on the materials and features in the bed. On average, you can expect to spend anywhere between $1500 to $2000.Are there bigger mattresses than California Kings?There are mattresses larger than California kings, these are referred to as oversized beds. Texas king, Wyoming king, and Alaska king are all three ultra-big beds that top the Cal king in terms of sleeping space. However, oversized beds are hard to find, so you’ll need to purchase these from a specialty retailer.Who are California king beds recommended for?California kings are a variation of the king designed for taller sleepers (those over 6 feet). The extra legroom these mattresses provide prevents taller sleepers’ feet from dangling over the edge of the bed.If you’re not over 6 feet tall, you’ll probably enjoy a standard king better for its additional wiggle room.Is a Cal king the same as two twin mattresses?No. However, a split-king is the same as two twin XL mattresses placed side by side. There is no way to make a split Cal king by combining two standard sized beds, these mattresses are specially made.ConclusionIf you or your spouse is on the taller side and requires more legroom to get completely comfortable—a California king mattress is sure to provide adequate space. These beds also provide enough width to allow sleepers to sleep soundly without being forced to the edge of the mattress.Larger mattresses do come with a higher price tag, but there is tremendous value in being able to get a good night’s sleep. If the size of your bedroom will accommodate a California king, the additional length may be just what you need for better rest.
