Our testers often use beakers of blue liquid and move across a mattress to test for motion isolation. Beyond the heat issue, there are other reasons why memory foam might not be the right choice for everyone. If you sleep on your stomach, many memory foam mattresses won't give you enough support, while if you're a combination sleeper who changes position a lot in the night, you may find that memory foam hug to be just a little too restrictive. And if you're of heavier weight, you could find that you sink too deeply into the foam and end up with too much pressure on your joints. All-foam beds are notorious for trapping heat, but the Nectar Premier Copper outperformed many competing models in our temperature control tests. Our temperature tests showed that it stays cooler than the average foam bed thanks to the phase change material and cooling gel infused into the comfort layer. The copper fibers are also intended to reduce heat retention on the surface.

The majority of today’s memory foam mattresses are sold online, making them more convenient to buy than those sold in stores. Online mattresses also tend to be more affordable than buying one in-store.

You can choose from five different profiles: 6, 8, 10, 12, and 14 inches. Each profile corresponds to a different firmness option — medium soft (4), medium (5), medium firm (6), firm (7), and firm (8). While the firmness differs between each model, we found the memory foam surface on all models conformed closely and offered excellent pressure relief. This greatly benefited our testers who experience pressure buildup in the shoulders and hips. The adaptive surface also excelled at absorbing motion and noise, which is ideal if you’re easily awoken by a sleep partner’s movements at night. Most online mattress brands offer free ground delivery, where the mattress is vacuum-sealed in a box and shipped directly to your doorstep. Foam beds tend to be the lightest, but in our experience it’s best to have at least one other person or moving equipment to help you move the box. The Nolah Signature 12 is slightly different from the other entries we included on this list. The mattress contains layers of adaptive polyfoam rather than traditional memory foam. This ensures comparable levels of pressure relief without the deep sinkage or excessive heat retention many people dislike about memory foam. Thanks to the polyfoam design, we recommend the Signature 12 for side sleepers and those who tend to sleep hot.

In general a good quality memory foam mattress should last for about eight years and quite possibly longer than that in the case of premium mattresses. Most memory foam mattresses come with a 10-year guarantee, which is a strong indicator of just how long the manufacturers expect them to last. Simba made its name with a range of quality hybrid mattresses including the Simba Hybrid Pro mattress, but then went on to add a pair of cheaper all-foam options, of which the Simbatex Foam mattress is the pricier and more advanced. Finding the best memory foam mattress is a top choice for anyone who wants a comfortable and supportive bed at a reasonable price. You'll find memory foam in most of the best mattresses, and people who prefer it generally appreciate its contouring body-hug and pressure-relieving properties. If you're troubled by sore joints, memory foam can help you sleep better and for longer. The Signature 12’s top layer consists of AirFoam, a proprietary open-cell material designed to contour evenly without trapping too much heat. A second comfort layer of high-resilience polyfoam cushioned the body and prevented our testers from sinking too deeply. This is followed by a denser AirFoam layer, which we found boosted support. The support core is composed of high-density polyfoam, and an organic cotton cover encases the entire mattress. Hot sleepers on our testing team found the Premier much cooler than competing foam beds. We attributed this to the cooling cover and phase change material. Like other memory foam beds, the Premier excels at motion isolation. The foam layers absorb movement on each side of the bed and prevent it from transferring across the surface, which can curb nighttime disruptions for couples and co-sleepers. The mattress is completely silent, as well.This is not intended to be a full statement of your rights under the Consumer Contracts Regulations.

How To Return A Product A comfort layer of gel-infused memory foam contours closely for a signature “body hug” feel. This layer also features phase change material engineered to react to your body heat and adjust the bed temperature throughout the night. Next is a transitional layer of high-density polyfoam, which helps evenly distribute weight. The high-density polyfoam support core improves spinal alignment by limiting sinkage. A quilted poly-blend cover encases the 13-inch mattress. A breathable cover made from a Celliant and polyester blend encases the mattress. During testing, the top memory foam layer evenly contoured to our testers’ bodies to relieve pressure-prone areas. The graphite and gel infusions in this layer are meant to conduct heat away from the body and dissipate it to keep you cool. Underneath is a layer of responsive polyfoam that evenly distributed weight and kept the spine aligned during our tests. The support core features high-density polyfoam, providing stability and limiting excessive sinkage.
