I bought one for me and one for my mother. I was about to replace a rock hard mattress and decided to give this a shot instead. I have a tempurpedic in storage that I have been missing huge. I love this topper even more than my expensive, hot mattress. There was a slight chemical smell, but it dissipated quickly, unlike my regular mattress. Also, I saw that some reviews had long delivery times - both toppers I ordered were delivered very quickly. I highly recommend the 3" topper.
