This is a really nice topper - very comfortable though it took some getting used to but memory foam is new to me. I really love it and have not found it to be too hot as some have commented. One word of caution....this thing is 4" tall! If you have a pillowtop mattress AND you add this topper you are going to have an issue keeping the fitted sheet on unless you have *really* deep pockets. This is the only problem I'm having at the moment. I will more than likely invest in a set of sheet suspenders to take care of the issue until I am able to purchase some extra deep sheets. (P.S. Regular Deep pockets are not deep enough with my pillow top). But overall, an excellent value for the money and it has completely solved the sagging "valleys" in my king size pillow top. LOVE THIS and would recommend!
