I had a regular memory foam topper on nmy bed but it lost a lot of it's support after a only 6 months. Now that I have the gel memory foam topper I'll never use anything else. I can't believe how comfortable sleeping is now. I don't have any morning backaches which I thought were normal no matter what I tried. I don't "sink" into the mattress which surprised me and there is none of the night sweating I hated so much. The support is wonderful...firm but not hard. I've already recommended this to friends and family who rave about it as much as I do. Now all 6 beds in our house have these toppers and guests seem to be staying longer with each visit. HMmmmm.
