Love the firm support the mattress gives. I had a pillow top mattress before (different brand) that was so comfortable but I would toss and turn and wake up with back pain every morning. I went with the perfect sleeper this time because I slept on this mattress a year ago and it was the best night's sleep I ever had. I have had this mattress for a week now and I longer wake up with back pain. The Serta is a quality mattress with good back support. I think it is a great value.
