I've been disabled for many years with back and knee injuries and suffer from chronic pain. Even my memory foam mattress wasn't starting to not be as helpful in getting a good night's sleep. This gel topper the best thing since sliced bread. It cushions my whole body and allows some sleep. It's the funniest looking thing with all the big bumps but, those bumps are the trick. I have a thick mattress pad and sheet over this gel pad and that's all I need. I've already recommended it to several people I know that have the same issues with pain and sleep. Plus you can't beat this price anywhere as they are usually at least twice what I paid.
