Nor sure if the memory foam pad works this way in general. I ordered the full size and it was shipped to me in a roll wrapped with plastics. The depth is 10 in as described. But the width is too wide and not fitting in the the full size bed frame we have. By tucking and pushing, still not fit perfectly with wavy surface. After couple night using, the general experience is with back pain and sore arm (if you sleep on your side). I think this is too firm for foam pad. However, the return cost is way too high....though shipping to you is $1. Wont recommend until you actually try it. hope this help for the cybershoppers.
