I am delighted that I purchased this product. It is a wonderful mattress and is sitting on a platform bed frame and still just right for sleeping. I did let the product recover for the full 48 hours that the manufacturer recommended. I have had another lower cost memory foam mattress and i see none of the issues I had with that one. It is actually more than 10 inches deep, the frame that it sits in is 10 inches deep and it is over the top of that by at least 1 1/2 inches. I'm very pleased and would recommend this mattress to anyone.
