[This review was collected as part of a promotion.] I had it for a week and its just wonderful, my back and body thank me everyday. Very comfortable. I used o have back pain and feel tired every morning. Now that I have used this mattress I feel more rested and no back pain. The quality of the mattress is always great, Serta doesn't disappoint.

[This review was collected as part of a promotion.] I received the SERTA PERFECT SLEEPER Cobalt Calm 14.5" FIRM PT a few weeks ago. I was a little concerned that it might be too firm but I can't sleep well on softer mattresses so I wanted to give it a try. Let me just say, I haven't slept better and I can't wait to crawl back in bed! It's firm but not hard. I have bad hips and this has even helped my hips to not feel sore in the morning after sleeping on my side all night. It stay cool throughout the whole night. That's big for me because I'ma very hot sleeper. I also love the fact it's anti microbial, so it will start feeling and smelling fresh longer than a typical mattress. Well done!

[This review was collected as part of a promotion.] After spending months looking for the right mattress that both me and my husband could agree on was tough, but when we came across this Serta Perfect Sleeper mattress, we fell in love! It is the perfect amount of softness and firmness, and maintains its shape and feel over time. We have always loved the Serta brand, and will definitely continue with our new mattress!

[This review was collected as part of a promotion.] This serta mattress is nice but I will say if you don't like a real firm mattress this isn't for you. The design on it is nice and the pillow top is nice to. It definitely needs a low profile set up too.

[This review was collected as part of a promotion.] We have had many Serta mattresses over the years and this one, like those, has not disappointed us. Serta continually makes an excellent mattress which lasts a long time. This one is comfortable for us; not too soft and not too firm.

[This review was collected as part of a promotion.] I bought PS23 SERTA PERFECT SLEEPER Cobalt Calm 14.5" MED PT for our new mattress and it truely is amazing. I love that it's not to soft or hard it's just right. It is firm enough to keep me from rolling yet soft enough to let me sink in. It is a game changer with sleeping.

[This review was collected as part of a promotion.] The Serta Perfect Sleeper Cobalt Calm 14.5" Medium Pillowtop Mattress deserves more than a 5 Star rating! My husband and I have been sleeping on it for about a week. We both have been sleeping better than we have in a long while. The medium firmness is not too hard, but not too soft either. The pillowtop adds extra comfort. Love, Love, Love!!!

[This review was collected as part of a promotion.] The Serta Perfect sleeper is spot on with its name. I haven't had a good night's sleep in a long time, constantly tossing and turning. But no more. I have slept like an Angel since the first night laying on it. You definitely can't go wrong with this 14.5 in mattress. If your looking for the best sleep ever, you found it l. I'd definitely recommend buying

[This review was collected as part of a promotion.] I wasn't expecting this mattress to be as pretty as it was when it arrived. I was blown away and am so thrilled that I can have a firm mattress to help my back. This mattress is great quality! I have had great sleep since switching!

[This review was collected as part of a promotion.] I need to upgrade my son's twin mattress and this queen size mattress is great! It is thick, and firm but not too firm. My son loves it! You do need deep pocket fitted sheets for it though - but that just shows how nice and thick the mattress is. I highly recommend this mattress!
