I ordered this to improve our new RV mattress. We have a memory foam topper on our mattress at home that is great. This topper just feels like puffy foam, no "memory" to it. Tried sleeping on it for 3 nights and my husband and I were not satisfied. Achy backs and not a restful sleep. I will not return it because it would be a major pain. We will just use it on one of the other beds in the RV.
