Ahhh Janet you hit a sensitive topic with me. I am a very very picky sleeper, husband and I have tried many combinations of mattresses, toppers etc... We have tried a soft mattress with a pillow top it was too soft then we switched with difficult child when he left and his was too firm, so we were looking at the tempurpedics and I couldnt see spending the money so we opted for a foam topper that we bought at Costco, I think its about 4 inches, it helped for a while I guess. I did notice that I was hot alot when I had it on my bed.
difficult child wanted his mattress back so we switched back to the original mattress with out the topper and thats what we have now but I have to be in the same spot on the bed to sleep.
Now, my mom used the topper on the bed downstairs which is actually difficult children mattress that he brought back when he came home and she LOVES it. She has a bad back and hips and she said she never slept better. My mom left to go home and difficult child put the topper on his futon and he loves it. My mom came back again and she was supposed to stay for 2 months so we went to Costco to get another one and they actually had one that had a down like pad over the memory foam and she liked that even better. It comes looks like a giant mattress cover its cool because it wraps around the mattress like a sheet and the memory foam is underneath it. I did have problems keeping the sheet on when I had it over my pillow top.
All in all, I wasnt impressed but my Mom and son and husband loved it.
I am too picky.
