In my continued effort to convert our home to a non toxic and natural environment I recently came across this article, Natural versus synthetic latex, I know I digress , but my beloved husband is/was a jock. Which means we are now addressing aches, pains , pins, replaced joints and arthritis. A perfect sleeping structure for us both has been challenging. Along with his challenges I suffer with allergies. We have gone through more mattress "trials" than I care to number. Fortunately we finally found one part that fit the bill, but there was the issue of the " topper" that was a continuous problem for my allergies. Enter "Natural Latex" . Game changer for me/us. Once again , information .
