We previously owned a Serta Perfect Sleeper mattress and box springs. It was not a firm mattress and my spouse had recently had trouble sleeping and woke with back problems. When we visited our son in Ohio last month, the hotel there had a Serta Perfect Sleeper Firm mattress and we slept wonderfully. When we arrived home we went online and purchased a mattress and have not had trouble sleeping since its arrival last week. I would highly recommend this mattress; however, don't take my word for it. I would recommend that you try out the mattresses at a mattress store to make sure the comfort level is acceptable to you. You may prefer a different comfort level, especially if you prefer a soft mattress.
