One answer is to re-use mattress materials as much as possible. In a mattress recycling center the foam, fabric, and wood are separated, baled, and sold to manufacturers. Steel is recycled at a scrapyard or re-used to fabricate other steel products.
Memory foam was a substance that was originally developed for use by NASA for soft beds for samples and things. When the company they worked with to create the substance was sold, memory foam because available for general usage. The main thing that memory foam is now used for is bedding, which makes sense. A piece of memory foam can go a long way to making a soft bed firmer, or a firmer bed softer.
Memory foam beds come in a vast variety of shapes and sizes. The early beds were little more than piles of straw or other organic materials. A vital change was lifting them off the ground, to avoid dirt, pests and drafts. To make memory foam beds much more comfortable, the top layer is usually a mattress. The bed frame is the third layer, as it lifts the mattress/ mattress-box spring right off the ground.
Like Sealy, Simmons didn't lead the way in development of viscoelastic, however they now manufacture their own version and even claim to have developed the 'next generation' of this type of mattress. It is true that the biggest complaint against memory foam has been a 'sinking feeling' - therefore not being able to move freely whilst lying down - and that it tends to 'cook the sleeper' because body heat is not dissipated quickly. Simmons claim to have solved both of these problems using their version of foam called NxG Advanced Memory Foam. From what I've garnered there does seem to be a small reduction with the quicksand feeling many customers complain about. With the claim as to heat reduction, I can't say one way or the other. The one overriding opinion is that the Simmons ComforPedic mattress is cheaper than a Tempur-Pedic mattress, though a little softer, and offers good value for money.
