[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!

[This review was collected as part of a promotion.] This mattress is a game changer for those experiencing back or hip pain. The mattress we have is firm. It provides just enough support so that when you get up in the morning you're not sore. It's definitely a thicker mattress than what we had had in the past and had to order deeper pocket sheets. Not an issue because it's the best sleep we've had in years. Highly recommend Serta mattresses!

[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 recieved the serta perfect sleeper firm mattress to try in exchange for my honest review. This mattress is firm and gave me the best sleep i have had. You dont sink into it. Helps my back really good. The mattress is 14.5 inches thick.

[This review was collected as part of a promotion.] This is a really attractive mattress. It is a darker blue color with a flowered design which helps disguise any staining that typically occurs on mattresses. The underside is flat so the mattress does not have to be flipped but I always find that flipping should be done on any mattress. We chose to go with an extra firm model because of back issues. It definitely takes some time to get used to such a firm mattress but your body will thank you later.

[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.] Great mattress! I don't see a lot of pillow top firm mattresses so I was very excited to sleep on this. As a stomach sleeper, this is perfect for me. I've had back pain with softer mattresses and do not with this one. I also like the height of the mattress. This mattress has very durable quality. I also put a mattress protector on it.

[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!

[This review was collected as part of a promotion.] So I got the Serta perfect 14.5 inch mattress and it is the most comfortable mattress I have ever been on. I love it. It has cooling gel swirled into the memory foam to give you a cool and restful sleep. I have never seen a mattress so beautiful. It has a cool to the touch mattress cover to also aid in cooling. It's a hybrid so memory foam on top then coils underneath for extra support and comfort. Serta know what they're doing because I've never slept better than I did the first night I got this mattress. My husband loves it too. He said it was amazing and beautiful to boot! I totally agree. I would definitely recommend to friends and family and when I'm in the market for another I believe it will be this one again!

[This review was collected as part of a promotion.] I absolutely love my beautiful mattress. This mattress is super super comfortable. It's nice and firm and soft at the same time. High quality mattress. I definitely recommend this awsome product. I look forward to comfortable sleeping.
