I had been searching for a foam topper for a 6" innerspring mattress and could not find any that really worked. The memory foam toppers on the market were much too soft and mushy and I would sink in too much and the edges would rise around me or form a lump of foam in front of me when I laid on my side. I would just sink and wake up feeling achy and tired. They did not seem to provide enough firm support. so I tried the Convoluted Eggcrate Foam Topper from foamforyou.com. Wow is all I can say, it worked so much better! I used the 1.5" Eggcrate Topper together with a 1" HD23 Medium/Soft Foam topper and together they worked perfectly to provide a softer yet firm support that was perfect. I no longer sunk in and felt as if the energy were drained out of me by memory foam! These toppers are not memory foam, and offer a much better soft, firm, springy support. No more energy drain from memory foam I am switching to these. Thanks to foamforyou.com online which provided an option for people who are tired and feeling rather "burnt out" on the memory foam craze, and excellent customer support and quick shipping.
