Memory foam, also called visco elastic foam, has been around since the mid-70s and made a big splash in the mattress industry over the past couple decades. In recent years, memory foam mattresses have become ubiquitous with the online mattress movement with brands like Casper and Tempur-Pedic making big impacts in the industry.
But what is memory foam exactly? It is a blend of polyurethane foam, which is a synthetic polymer, that is slow response and soft to the touch. There are a variety of foam manufacturers around the United States and abroad that supply mattress makers. Some mattress companies also create their own special blend of foam for their specific feel. For example, Tempur-Pedic has its own proprietary blend called Tempur® foam.
Over the years, memory foam and other polyurethane foams have become increasingly cheap to make. This has led to the advent of cheaply made mattresses, by brands large and small that have caused toxicity concerns. However, there are a few independent organizations that certify low emission foam, such as the CertiPUR-US standard. If you are sensitive to chemicals, make sure to check the certifications!
The best memory foam mattresses aren't purely memory foam. Their top layer is generally soft to the touch, but their middle and bottom layers are higher density and firmer to provide better support than memory foam alone. The most comfortable foam mattresses are medium to medium firm so they don't swallow you, but provide a gentle contouring to keep you confortable. Tomorrow, Nolah and Nectar do a great job at this!
Memory foam tends to sleep hot both because of the materials used and because it hugs more surface area of your body, which is why it is so important to find a mattress that sleeps cool. Bear mattress has a Celliant® cover that diffuses heat into infrared light. Its design ensures that you'll stay cool through the night!
