[This review was collected as part of a promotion.] This mattress was even more than I expected on the overall. It's nice and thick at 14.5" which is actually really tall. It has a topper so to speak that's a little softer than the rest of the mattress so it's not super stiff. It did take a little time to get used to the firmness, but once broken in some it was so very comfortable. I've slept great on this and am loving the firmness.

[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 got this bed and was so excited to start using it. I have pain in my lower back and this mattress is magic! It's super thick and comfortable. I enjoy that when my significant other gets up, it doesn't wake me up. Great quality.

[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.] I needed to replace my bed in my bedroom and went to serta to get a new mattress! This mattress is so comfortable and worth every penny! Keeps cooler than a normal bed and now I don't wake up hot or with achy back and bones from a broken down mattress! Serta js the way to go!

I can't wait to sleep on this new mattress tonight! I have recently had total knee replacement surgery and have been on my back on my couch for six weeks. I have been a Serta perfect sleeper lover for many decades. I highly recommend Serta perfect sleeper mattresses.

[This review was collected as part of a promotion.] This is an amazing mattress! The extra pillow top is where the manic is at. I seriously might upgrade to a king just because it is that comfortable! Serta is an amazing brand that goes above and beyond for their customer.

[This review was collected as part of a promotion.] I am so, so happy I have this mattress. This thing is AMAZINGLY comfortable. Of course, mattress firmness is a personal preference so I can't say it'll work for everyone but this mattress is the perfect blend of firm and plush with the added benefit of cooling. It's not your typical mattress - the top layer is cooling and plush and my body feels supported all over as I sleep. It is so thick that I was afraid my regular bed sheets might not fit but that wasn't a problem at all, thankfully. You get what you pay for and this mattress is worth it's weight in gold! I would have given it more stars if I could.

[This review was collected as part of a promotion.] This mattress is amazing quality and my old mattress looks like a joke next to it! No issues with stitching or fabric and it's really plus amd comfortable, while staying nice and firm. My husband has some back pain and told me this mattress is helping a ton to reduce that. There has been no sagging or pressure marks in the mattress yet and I feel this will last a super long time. I'm really impressed and a great quality bed really makes a huge difference in your whole life.

[This review was collected as part of a promotion.] My wife and I have had this mattress for about a month and have found it very comfortable. We opted for the medium one and it is just right. I tend to be too warm when sleeping and I havent noticed that since using this mattress.
