Memory Polyurethane Foam: Visco-elastic differs from conventional polyurethane foam in that it uses a high-hydroxy polyol and different isocyanate.
Latex Foam: There are two types of latex: natural latex (also known as "natural rubber latex", which is what we sell) and styrene-Butadiene rubber (SBR, or "synthetic latex"), which is what regular mattress stores sell.
Solvents show up in mattresses because they are critical ingredients in many adhesives used to bond together mattress layers and wood frames. One of the most common solvents used today in the mattress industry is based on methylene chloride (METH), which is a suspected carcinogen."(1)
Health Hazards of Common Mattress Solvents
Chemical Health Hazards (1)
|| Toxic to the lungs, liver, and brain
| Respiratory tract irritant
|| Respiratory tract irritant
| Carcinogen and neurotoxin
|| Know to cause testicular degeneration and methemoglobinemia
|| Toxic to the liver, kidneys, and brain
Studies show a dramatic increase in cancer 10 years after the initial use of polyurethane foams in America. Keep in mind that the chemical industry has powerful lobbying firms serving them in Washington. Remember when our government approved the use of Asbestos? I believe the awareness of toxic mattresses is similar to where the cigarette industry was just 20 years ago.
