The quality of the topper is excellent. Unfortunately it didn't work for me. When I first laid on it it was ahhhhh!!!! Within 2 hrs I felt like I was in gully. It is way too soft for my back. The "Mem-Cool" is exactly that. Other brand memory toppers become hot. Not this one. The memory cool does work. I was very disappointed to have to send it back. I was hoping it would be the answer to some of my back issues. If you just need a little more cushion & coolness this would be perfect for you.
