I couldn't afford to buy a brand new mattress and I have been sleeping on a feather bed on my mattress which hasn't been easy on my back. I have herniated discs in my lower back and this mattress topper has been a wonderful solution for me! The memory foam is very comfortable and helps even out my weight so that my hips are not killing me as I sleep! This is a wonderful product at a price you cannot beat! I have been very happy with my purchase!!
