That's great advice thanks astern.

I don't have MCS, but I had the experience at the beginning of last year of staying in a unit affiliated with a hospital that I had to visit and the moment I walked into the bedroom I could smell this awful smell. I can still smell it just thinking about it. There were foam pillows on the beds. I had to remove them from the room because the smell was so disturbing.

I have a lot of bamboo and hemp fabric products. Tea tree mattresses were just coming in when my babies were born. They're made much better now. I like my organic cotton japanese shiki futon.

thanks again for info about the memory foam gas problem. I guess basically it's deteriorating rubber?? [I notice a lot of handles on appliances tend to start deteriorating too. They get sticky and yuk. Probably the same process of decay.]
