Wonderful. I got the Sealy Medium  Memory Foam mattress for my guest room, where my Mom sleeps when she comes to stay, she suffers from arthritis. She has been having trouble sleeping,she said its hard finding a comfortable spot on her old mattress. I saw this one and thought I would try it.  She is very happy with the mattress. She has slept better than she has in years. No more painful, sleepless,nights tossing and turning trying to find a comfortable position. She says all positions on this mattress are comfortable. She is getting one for her house too.
