Natural Form Garden Inn Mattress - As soon as the mattress was taken out of the plastic bag and set up on the bed, it started to smell a strong chemical smell. I opened the windows (winter time) to air it out. We attempted to sleep on it but with the windows closed, the smell woke us from a sound sleep anytime we rolled to our sides. After multiple phone calls to WCW, we were told any replacement 3 inch foam top layer would smell the same. We bought another brand of 3" foam and asked WCW for reimbursement. They refused. We are out $500. Don't buy this mattress.
