The Tulo mattress is 10 inches thick and contains 2 inches of memory foam, 1.5 inches of convoluted foam, 2 inches of resilient foam, and 4.5 inches of poly-foam. The soft, knit cover provides a soft, plush sleep surface.Both the Tulo and Tulo Hybrid mattresses are available in soft, medium, and firm. We focus on the medium, since a medium feel is a great option for most sleepers and a good firmness if you aren’t sure what you need or want. Each mattress type contains the same layers of foam, but the support layer varies in density depending on the mattress (i.e. low- density for soft, medium-density for medium, and high-density for firm).The top layer of memory foam contains titanium particles to pull heat away from the body. For further cooling, ventilation holes are punched through the memory foam to improve better airflow.Convoluted foam or egg crate-shaped foam allows for better air circulation through its open channels.Resilient foam acts as a transitional layer between the comfort layers and support layer. This foam provides deeper compression for more pressure relief.The base poly-foam layer may differ in density, depending on the firmness level of the mattress. The medium mattress has a base with medium support, complementing the top layers. The poly-foam provides ample support with little risk of sagging.Tulo includes a 120-night sleep trial and a 10-year warranty.

Most bed in a box brands are sold online only. These types of mattresses have a lower price tag and are more convenient, both for customers and mattress companies.Online vs. In-StoreBecause bed in a box mattresses are sold directly to the customer, these online mattress brands save money by cutting out the middleman (sales commissions, stocking fees). They can create beds made of higher-quality materials for a lower cost. Online mattresses also come with extended sleep trials if the customer doesn’t like the bed.Traditional mattresses sold through brick-and-mortar stores charge more for their beds to make a profit. While customers get an advantage in trying out a new mattress before buying, they do so under pressure to buy from salesmen and may receive a limited sleep trial. For many, these advantages make online stores one of the best places to buy a mattress.White Glove-DeliverySome mattress companies, both online and in-store, may offer a white glove delivery service, either free or for an extra charge. White glove delivery assembles the new mattress in your home and removes your old mattress, taking the hassle out of setting everything up.What to Look for in a Bed in a Box MattressBefore purchasing the most popular mattress brand on the market, make sure it’s the right one for you by considering mattress type, quality, body weight, sleeping position, cooling features, and available sleep trials, return policies, and warranties.Mattress TypeEach mattress type provides their own unique feel and include both benefits and drawbacks. Some sleepers may want a mattress with excellent motion isolation like memory foam or latex, while others may prefer a bouncier mattress, like an innerspring.Memory Foam MattressMemory foam is one of the most popular mattress types in the industry due to its conforming, pressure-relieving properties. Memory foam also sleeps silently and has excellent motion isolation. A drawback to memory foam mattresses is heat retention because of its dense structure.A memory foam mattress contains a comfort layer of memory foam and a support layer of high-density foam.Innerspring MattressInnerspring mattresses are commonly found in most households. Innerspring mattresses have a bouncy surface and exceptional cooling through the coiled support layer. Some drawbacks to an innerspring mattress include little to no pressure relief, less motion isolation, and noise potential.An innerspring mattress contains a thin comfort layer of foam or fiberfill (usually in pillow top form) and a support layer of innerspring coils.Latex MattressSimilar to memory foam, latex also conforms to the body’s natural curves to relieve pressure points. Unlike memory foam, latex is cooler and has a responsive bounce. A typical latex bed contains a comfort layer of latex and a support layer of either high-density foam or latex. Latex mattresses can be expensive, depending on the type of latex they contain.Latex foam comes in two forms— synthetic and natural. Synthetic latex is made through a chemical process, while natural latex is created from rubber tree sap. The most common types of natural latex are Dunlop and Talalay. Dunlop is denser and more durable than Talalay. Talalay has added polyurethane fillers for its signature soft feel.Hybrid MattressA hybrid mattress combines memory foam and innerspring coils to form the perfect bed. Memory foam relieves pressure points and isolates motion while innerspring coils provide edge support and cooling. While hybrids provide the benefits of both mattress types, they also give drawbacks including overheating, less pressure relief, and motion transfer.A hybrid mattress contains a comfort layer of either memory foam or latex (must be at least 2 inches) and a support layer of pocketed coils.QualityMattresses are a big investment— it may be tempting to choose a bed at a lower price point to save a few bucks, but the quality may not be as good. Low-quality mattresses break down within 1 to 2 years of regular use, and you may end up spending more to replace the mattress sooner.The average price tag for a high-quality mattress is $1200. To determine mattress quality, look at the foam’s density and ILD rating, and the coil’s gauge and count. These factors will determine if a mattress lasts 7 to 9 years or less than 2 years.FoamIn determining foam quality, check the foam density and ILD rating.Foam density determines how the foam supports the body by measuring how long it takes for the foam to spring back to its original shape. Foam density is measured in pounds per cubic foot (PCF). The higher the density, the slower the recovery. Memory foam mattresses contain a mix of low- and high-density foams. Memory foam comfort layers vary in density depending on the brand.Low-density: 2.5 to 3.9 PCFMedium-density: 4.0 to 5.9 PCFHigh-density: 5.5 PCF or higherILD, or Indentation Load Deflection, rating determines the foam’s firmness by measuring how much pressure it takes to make a 4-inch indentation on the surface. The higher the number, the firmer the foam. Most foams range between 8 to 20— 10 is the ideal number for the best support in a comfort layer.CoilsTo determine coil quality, take a look at the coil count and coil gauge.Coil count is the amount of coils in a single layer (usually in the support layer). A high-quality mattress contains 500 to 1,000 coils. Avoid mattresses containing less than 300 coils— it could be the sign of a poor-quality bed.Coil gauge is the thickness of a coil, measured in millimeters. The thicker the coil, the more durable the material. Lower measurements have thicker coils, with softer coils from higher measurements.Thickest: 12mmThinnest: 18mmWhile thinner coils aren’t a bad thing— especially since some mattresses have innerspring comfort layers— be careful of mattresses with support layers containing only high-gauge coils. It may lead to premature sagging and breakdown of materials.Body WeightBody weight has a great influence on the mattress you choose. Body weight is divided into three groups; light, average, and plus-size. Choosing a mattress based on your current body weight and sleep position will ensure a better night’s sleep. For example, a plus-size sleeper may feel a medium-soft bed is too soft and lacking support.LightLight sleepers weigh less than 130 pounds. They need a softer mattress to enable body-contouring pressure relief.AverageAverage sleepers weigh between 130 pounds and 230 pounds. A medium feel is the best choice for an even balance of comfort and support.Plus-SizePlus-size sleepers weigh more than 230 pounds. A firm mattress might be the best option to provide support without risk of sagging.Sleeping PositionEach sleep position requires a certain level of comfort and support to fill in the gaps between the body and the sleep surface. Keep your favored sleep position in mind when looking for a new bed.Side SleepingSide sleeping is the most common sleep position. It allows for better breathing, less pressure on vital organs, and reduces acid reflux symptoms. Placing a pillow between the knees prevents spinal misalignment.If you need a mattress for side sleeping, choose something soft to medium in firmness for optimal pressure relief in the shoulders and hips.Back SleepingBack sleeping enables natural spinal alignment because of the back’s direct contact with the sleep surface. Back sleeping comes with the risk of developing sleep apnea— gravity causes the tongue to fall back, obstructing airways, and the collapse of soft tissue at the back of the throat.A medium to firm mattress is the best mattress option for back sleepers for enhanced lumbar support and pressure relief in the shoulder and hips areas.Stomach SleepingStomach sleeping is the least common sleep position and the unhealthiest because of the amount of pressure placed on the spine. This pressure may lead to neck strain (twisting and holding the head at an awkward angle to breathe) and back pain (gravity pulls weight down, forcing the spinal curvature to straighten). Placing a thin pillow under the hips eases spinal pressure.The best mattresses for stomach sleepers are typically medium-firm or firm, as these beds keep the body resting on top without deep sinkage.Combination SleepingCombination sleepers switch between 2 to 3 sleep positions each night, tossing and turning regularly. Combination sleepers may receive the benefits of each sleep position, like better breathing and natural alignment, but they also get the drawbacks, including risk of developing sleep apnea and back pain.A good mattress for combination sleepers maintains spinal alignment and provides even comfort and support for each sleep position. Usually, combination sleepers choose medium mattresses to achieve good sleep.Cooling FeaturesHot sleepers or those who prefer a cooler sleep surface may want to look for a bed in a box mattress with cooling features like breathable, plant-based foam or innerspring coils.FoamSince traditional memory foam is known to retain heat, choosing a mattress with cooling memory foam, like plant-based or cooling gel regulates temperature and reduces the risk of overheating.Plant-BasedPartially replacing petroleum with plant oils produces a breathable, more responsive memory foam. Plus, plant-based foam has little to no off-gassing odor.GelGel is either mixed in or swirled during the manufacturing process. Some gel memory foam contains gel beads. Gel foam absorbs and disperses body heat.Open-CellTraditional memory foam does have a small amount of open-cells, but not enough to combat heat retention. Injecting memory foam with air creates more air pockets, enabling better air circulation inside the mattress.Copper or Graphite InfusionsInfusing copper or graphite into the memory foam pulls heat away from the body and may improve local blood flow.CoilsThe open structure of innerspring coils allows for better airflow inside the mattress. Both innerspring and pocketed coils have more space for air to pass through, though it might be less inside a pocketed coil layer because of the extra fabric.Sleep Trials, Return Policies, and WarrantiesSleep trials, return policies, and warranties are ways manufacturers reassure customers of a quality mattress purchase. Mattresses are a big investment, and ways to protect that investment and ensure it lasts makes the cost worth it.Sleep TrialsA sleep trial is an at-home trial period where the customer can try out a new mattress within an extended time. Most sleep trials last between 90 to 120 nights. Should the customer not like the mattress, most mattress companies will issue a full refund.Return PoliciesA return policy is an okay substitute if a sleep trial is unavailable. Return policies last about 30 days, allowing a good amount of time to adjust to the new mattress. If the customer isn’t happy with the bed, they can return it for a full refund, but be cautious and read the fine print— some companies will only accept returns if the mattress is inside an unopened box.WarrantiesA mattress warranty covers any manufacturing defects which could cause damage to the bed and sagging greater than 1 inch (measurement varies depending on the brand). Most mattresses come with a standard 10-year warranty, though some mattress companies provide longer warranties. A warranty only applies to the original purchaser and can’t be transferred to another person.Other Things to ConsiderHow long do bed in a box mattresses last?Bed in a box mattresses last just as long as beds you can buy in-store, so their expected lifespan more or less depends on the materials used in the mattress. Most high-quality foam mattresses last between 7 to 9 years, while hybrids and innersprings usually only last 5 to 7 years. You can also check out reviews of the product to see how long other customers have owned their mattresses.Does a bed in a box need a box spring?It depends on the type of mattress— memory foam and latex mattresses typically don’t need a box spring, but innerspring and hybrids might. Double-check with the mattress manufacturer before committing to a new mattress.Can you sleep on a mattress in a box right away?Generally, you should wait between 24 to 48 hours to allow the mattress to fully decompress before use, but most bed in a box beds on the market today have a shorter resting period, depending on the brand.What is the number-one selling bed in a box?It’s hard to say, but currently, the best-selling bed in a box on Amazon is the Zinus Green Tea Memory Foam mattress. Zinus’s mattress is so popular because it comes in different firmness and thickness options, so sleepers can really customize their new mattress. Plus, people love it because it’s infused with green tea extract to wick away body heat and keep the bed smelling fresh and clean.Are spring bed in a box mattresses better than foam models?Not necessarily, spring mattresses have plenty of benefits, but so do foam beds, so to determine if one is better than the other, it’s best to compare benefits and choose which one interests you more. Spring mattresses are not as common as foam mattresses when looking at bed in a box brands, simply because foam is easier to compress than springs, but that doesn’t mean that one type of mattress is necessarily better than another.ConclusionThe convenience of a bed in a box mattress makes it the best choice for any type of sleeper. Bed in a box mattresses are made from quality materials with extended sleep trials to ensure a good fit. If you struggle with sleep, a bed in a box mattress might be the solution.About the author Andrea Strand CERTIFIED SLEEP COACH Andrea Strand is a Certified Sleep Science Coach.
