The most common materials in all mattresses are foam. A soft, motion-absorbing material that helps regulate temperature and relieve pressure points. It is used as a filler in mattresses with a padded top and mattress covers, wool. This environmentally friendly material offers sufficient support throughout the mattress.
In addition, it recovers its original shape more easily than memory foam. Many people describe latex mattresses as a combination of internal springs and memory foam. Different versions were circulating, but it wasn't until the 1990s when the memory foam mattress really hit the market. By definition, these mattresses have at least one comfort layer made of memory foam, and some also have transitional layers of memory foam for added support.
And what exactly is memory foam made of? A polyurethane foam: a material made for the first time in the 1950s by mixing water with halocarbons or hydrocarbons. Nowadays, memory foam mattresses are generally made of polyol mixed with water and a chemical compound called diisocyanate. Latex mattresses vary in terms of construction material: 100% natural organic latex mattresses cost more than synthetic blends.
