I already have a latex mattress and another latex mattress topper -- a 3 incher. So, I am familiar with latex. Good latex is relatively resistant to taking body impressions. It gives under pressure and bounces back into shape when the pressure is off. That's one of the reasons I like it. My 3 inch topper has been slept on almost every night for 6 years and still does not show body impressions. Unfortunately, my husband and I slept on the E.C.O. 2-inch Luxury Latex King Mattress Topper for three nights and there were "valleys" where we slept and a noticeable "hill" in the middle of the bed. My husband and I are not large people -- probably a bit smaller than average. So this was both surprising and disappointing. I bought this topper because the other reviews were uniformly great. Now I wonder whether I got a defective topper or whether the other reviewers just didn't know what to expect from quality latex.
