Heavy sleepers or those with severe joint issues may not be comfortable sleeping on an air mattress. The benefits of air beds include a lightweight design, low price, and easy storage. It is not recommended for anyone to sleep on an air mattress long-term.HybridHybrid mattresses are the perfect crossover between traditional spring beds and a memory foam mattress. A hybrid bed contains a 2-to-3 inch-thick top comfort layer made of latex foam or viscoelastic foam. Beneath the comfort layer, a hybrid mattress is supported by a coil base. Benefits of hybrid beds include even weight distribution, edge support, and some body-hugging.Hybrid mattresses are excellent for side sleepers seeking a bouncy bed. Innerspring mattresses can feel too firm against their bodies, failing to relieve pressure points.InnerspringInnerspring mattresses are an old-school mattress style. Traditional innerspring mattresses are known for their breathability and superior edge support. This means you don’t have to worry about rolling off the side of the bed. Innerspring beds feature a thin top comfort layer and a steel coil support system.An innerspring mattress is cheap and needs to be paired up with a box spring. Light sleepers or those with intense joint support needs should opt for a different mattress.Plus, coil mattresses are noisy and may require a mattress topper for some to sleep without body aches.LatexLatex mattresses can contain synthetic, natural, or a blend of both types of latex. There are two types of foam. Dunlop latex is traditionally natural. Talalay latex contains a blend of natural and synthetic materials. Latex beds have less motion transfer and a cool, breathable sleep environment.Additional benefits associated with latex mattresses include a responsive design, bouncy support, and no sinking into the bed. Organic latex mattresses can be expensive, and they aren’t ideal for those looking for a bed with a body-hugging sensation.Memory FoamMemory foam mattresses are made up of several dense layers of polyurethane foam. Different layers of foam hold your body and hug your joints. This cradling feeling is beneficial for lightweight sleepers or those with sore joints. When you rest on a memory foam mattress, you won’t hear your partner as they move in their sleep or exit the bed.Memory foam beds trap body heat. However, this issue can be fixed by purchasing a mattress with a built-in cooling gel. Gel memory foam mattresses are excellent cooling beds, wicking heat away from the body.Side sleepers and combination sleepers are most comfortable on a memory foam bed. However, since memory foam mattresses come in various firmnesses, anyone can find a memory foam mattress right for them.WaterbedWaterbeds have been around for centuries. Traditional waterbeds are known for springing leaks and not having enough support. However, today’s waterbeds are more durable and supportive than their predecessors. They are designed with a vinyl mattress containing one or several water bladders.The water chambers hold the water and are the main form of support for this style of mattress. Modern waterbeds come with temperature regulation, perfect for hot and cold sleepers. Waterbeds have been shown to decrease back and spine pain as well as help with muscle relaxation.Factors to Consider When Mattress ShoppingPrice: What is your price point? How flexible can you be? Do you need a well-made budget mattress or can you afford to splurge on a bed with bells and whistles?Durability/longevity: Are you looking for a mattress that can last for one or several decades? Some mattress types have longer expected lifespans than others.Frame type: Certain mattresses, like waterbeds and memory foam beds, cannot be paired with metal bed frames. In addition, latex mattresses shouldn’t be used on a slatted bed frame.Room size: You always need to factor in bedroom size when selecting a mattress. You need a minimum of 2-feet of open space around the perimeter of your bed.Bodyweight: Larger or heavier sleepers need a bigger mattress. These individuals also need a mattress that is supportive and won’t leave them feeling trapped or sunken in.Sleep position: Side sleepers, back sleepers, stomach sleepers, and combination sleepers all have different support needs. You and your partner’s sleep style impact the type of mattress and firmness level you’ll need.Co-sleeping vs. sleeping alone: Choosing the right mattress is easier for those who sleep alone versus those who must consider the needs and wants of a partner. Those with different sleep schedules need a bed with good motion isolation. Similarly, a mattress for couples should be noise-free for undisturbed rest.Support needs: Whichever mattress you choose, it should be able to alleviate pressure points and minimize your pain at night. Consider your specific support needs. For example, stomach sleepers benefit from firm mattresses with enhanced support.Mobility: Getting into and out of bed can pose big fall risks for those with limited mobility. Pick a mattress that is easy to get out of and doesn’t force you to bend down to get into bed. Mobility issues can also influence how much your mattress should weigh; a heavy mattress can make changing your sheets challenging if you have difficulty moving and lifting objects.Allergies/skin sensitivities: Do you need a mattress for allergies? Those with allergies or skin sensitivities are best suited with a natural latex mattress. However, those with a latex allergy should avoid any bed or bedding with latex in it.Temperature/climate: If you’re prone to overheating, you may need to steer towards an innerspring mattress or a latex mattress. Those who suffer from night sweats should try a cooling memory foam mattress with a gel infusion.Testing Out a New MattressTesting out a new mattress before you buy it is important.
