We receive a lot of questions about what filling materials are best for original mattresses, and today the Aero sales team will analyze the advantages of various materials for you. We sell latex foam products because we firmly believe that latex foam is the best type of foam for mattresses and mattress covers. Latex foam has several significant advantages over memory foam and polyurethane foam.
Latex CV Foam
Latex foam is a foam produced by vulcanizing liquid latex into solid foam. The vulcanization process uses heat and accelerators such as zinc oxide to crosslink the latex particles with sulfur. Latex foam can be produced using natural latex harvested from rubber trees or synthetic latex produced from petrochemicals. All latex foams we sell contain only natural latex, never any synthetic latex. Latex foam provides precise, precise support and responds instantly to your every move rather than the hard mattress for back pain. Latex foam doesn't "sink" and "bottom out" when you sleep on it as the night goes on. It maintains constant support and doesn't soften as it warms. This makes it very easy to move throughout the night without interrupting any sleep.
Precise contoured support allows certain areas of the body to sink further into the mattress while others are supported. This is especially helpful for side sleepers because they need more strength in their shoulders and hips, but more support in their abs. Latex foam is one of the most durable types of foam available. Latex mattresses and mattress covers will last longer than those made with memory foam and polyurethane foam. We often hear stories from customers who have used latex mattresses for over 20 years. Latex foam scores highly on all foam durability tests that simulate prolonged use.
Polyurethane Foam
Polyurethane foam (also known as polyfoam) is the cheapest and lowest quality foam used in mattresses and mattress covers. Polyurethane foams are mainly composed of compounds derived from petrochemicals. Many mattress manufacturers use polyurethane foam as the top layer of spring mattresses. This is done mainly because the price of polyurethane not high , not because it is of high quality. Recently, many online mattress retailers have started using polyurethane foam as the bottom layer of their mattresses instead of coil springs. Polyurethane foam can be easily compressed due to its low density. This allows many online mattress retailers to save on shipping costs, but also results in a shorter lifespan for many of these mattresses.
Polyurethane foams come in several different varieties and densities. In general, high-density polyurethane foam is more durable, while low-density polyurethane foam degrades quickly (sometimes within a year). Even high-density polyurethane foam is less dense than latex or memory foam. All polyurethane foams, regardless of density, degrade faster than any good quality latex foam. Polyurethane foam can add some softness and support, but it won't provide the precise support associated with memory foam or latex foam. Polyurethane foam tends to collapse faster when pressure is applied. Because of this, it doesn't offer the same precisely contoured support that latex foam is known for.
Memory Foam
Memory foam (also known as viscoelastic polyurethane foam or temporary foam) is a type of polyurethane foam that contains added compounds that change the way it feels. This gives it the "slow-moving" properties that memory foam is known for. For example, it retains your handprint for a few seconds when pressed. Like polyurethane foam, memory foam is primarily composed of compounds derived from petrochemicals.
Memory foam is generally denser and more expensive than regular polyurethane foam. Memory foam does provide a more precise feel than polyurethane foam. While it offers a precise feel, it's not as supportive as latex foam. We usually talk to people who have memory foam mattresses or comforters but can't stand the unsupportive, sinking feeling they experience on them. Covering memory foam is actually one of the main reasons people buy our mattress covers. Unlike latex foam, which responds instantly and provides continuous support, memory foam responds slowly and sinks deeper the longer you apply pressure. The sinking of the memory foam makes it more necessary to move during sleep, but the slow response of the sponge makes it very difficult to move without disturbing sleep.
Memory foam is also thermally reactive, which means it absorbs heat and softens as the temperature rises. This adds to the "sinking" problem mentioned above. As the memory foam heats up from your body, it becomes softer and sinks more. As your body sinks further into the foam, you get hotter. This continues until many wake up to find themselves hot and trapped in one spot on their mattress. Newer versions of memory foam exist that are designed to reduce heat (often called "gel foam"). While these foams contain chemicals that make the surface of the foam feel cooler, many people experience the same thermal issues with gel foam.
