Memory Foam products, commonly known as Polyurethane foam, are quite flammable. To counter this problem the Polyurethane foam manufactures have for the past 30 years used "flame retardants" or "combustion modifyers".  These include Poly Brominated Diphenyl Ethers "PDBE", Melamine, other halogenated (chlorine or bromine containing) compounds in conjunction with organic phosphorus compounds such as phosphate esters.

PDBE Health and environmental concerns

Since the 1990s scientists have questioned the safety of PBDEs. People are exposed to low-levels of PBDEs through ingestion of food and by inhalation. PBDEs bioaccumulate in blood, breast milk, and fat tissues. Personnel associated with the manufacture of PBDE-containing products are exposed to highest levels of PBDEs. Bioaccumulation is of particular concern in such instances, especially for personnel in recycling and repair plants of PBDE-containing products. People are also exposed to these chemicals in their domestic environment because of their prevalence in common household items. Studies in Canada have found significant concentrations of PBDEs in common foods such as salmon, ground beef, butter, and cheese.[3] PBDEs have also been found at high levels in indoor dust, sewage sludge, and effluents from wastewater treatment plants. Increasing PBDE levels have been detected in the blood of marine mammals such as harbor seals.

Published studies express concern because exposure to PBDEs impairs development of the nervous system. PBDEs have also been shown to have hormone disrupting effects, particularly on estrogen and thyroid hormones. The U.S. Environmental Protection Agency (EPA) noted that PBDEs are particularly toxic to the developing brains of animals. Peer-reviewed studies have shown that even a single dose administered to mice during development of the brain can cause permanent changes in behavior, including hyperactivity

So, budgy and zzzombie:  is the practical application of the knowledge presented in this thread that the best/only way to avoid significant offgassing in a mattress is to get an all natural latex mattress?

Believe it or not...its actually probably the most cost effective way to do so.  The alternative is to get something like a Vi-Spring or a Hastens which will be a lot more money.  Or you could do somelike like an all natural futon....still not going to be truly cheap, probably as much or more than a regular pillowtop mattress, and arguably not the most comfortable for most people.

Offgassing PU is not the main concern. Long term health issues caused by sleeping, breathing & absorbing the insideous "fire retardants" into your body from this material can persist for years. That is my concern.

all Natural Latex does not have that issue.
