I have tried and LOVE the Serta icomfort series beds (memory foam). I had purchased a Serta memory foam mattress and a topper 2+ years ago from Overstock and love it, love it, love it!!! BUT...as I get older I wanted a softer bed. So instead of purchasing the icomfort, I decided the only layer missing was the latex on my bed soooo, I purchased this Talalay 3" mattress topper and it is EXACTLY what I wanted. Mine is medium and I could have even went to the firm, but a soft would have been way too soft. Now I have a 21/2" topper of 5 lbs. memory foam, the 3" latex layer and an 8" serta memory foam. It's as close to an icomfort (revolution/savant) without the cost. FANTASTIC. And I purchased them from Overstock!!! Thanks, Overstock! Great prices for great products!!!! A MUST BUY!
