I have had questions about mattress covers for the chemically sensitive. When I first became aware of my chemical sensitivities and before I realized I had to get rid of my mattress and everything else, I purchased a barrier cloth mattress cover and pillow covers similar to the picture above which is available from Amazon.com. The fabric is a very tight weave and helped with some of the products and gasses in my mattress. However, for me, the barrier cloth also had its own particular odor and I had to wash it a few times to make it safe enough to use. For those of you who still have the luxury of a real, honest to goodness mattress, do you have mattress covers? If so, what do you use?
