My husband has some back pain that seems to feel better when he sleeps on a very firm mattress. We chose this mattress to replace one that was too soft for him. This mattress is very comfortable for both of us. We do not feel each other moving at night and both of us wake up refreshed in the morning. This bed feels comfortable and sturdy and has not yet formed any indentations where we sleep. I was given this bed in exchange for my honest review and I can say we would certainly purchase this mattress again!
