My husband I were both suffering with lower back pain every day before this mattress, I have heritary back problems coupled with fibromyalgia and my husband has bad hips. We were worried at first the firm was going to be too hard. Thankfully the adapting foam gives us both just the right amount of support without feeling like concrete. The only thing that still gives me pause every night is how hard it feels while getting into bed. I'm sure it's just from years of sleeping on a super soft mattress and I'm just not used to it. Overall, very satisfied with my purchase and can't really see myself sleeping on anything else ever again.
