I have only slept on a memory foam mattress one time. It was in Ponca City when we were there for hyperbaric therapy for Isabelle. We ended up staying in Jane’s sister’s beautiful home and she had that kind of mattress. It was interesting. It really did take the shape of your body and if you toss and turn a lot it may not be for you. It seemed to take a little bit to adjust to movements. Overall I thought it was pretty comfortable though and wouldn’t mind having one of my own!
