The mattress was comfy for about a month or two, then it seemed to quickly have sagging areas along the side (sitting on side of bed) and in the middle. We sought a new mattress due to pressure points experienced with out Temperpedic mattress. We were assured that that would not be an issue with this new Serta mattress. Well. I am now regretting that decision.

[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 love this mattress! I'm so happy that we got it! We switched from a 9 year old memory foam mattress and the difference is incredible. Our old mattress was very hot and developed a hump in the middle, with two valleys on the sides, where we sleep. This mattress is not hot at all! It is also pretty firm compared to our old one. The pillow top is really nice and firm too. It is a deep mattress, but I haven't had any issues with sheets popping off the corners. My husband and I are side and back sleepers and it seems to be perfect for us!

[This review was collected as part of a promotion.] We were hunting to replace our 15-year old mattress. After doing some research, we liked the Serta brand and decided to try this one. We like that it's a combination of spring and memory foam. It helps making the bed steady, and when we move, the bed stays in place. So far, we like and enjoy the mattress.

[This review was collected as part of a promotion.] I haven't slept this good in months! The PS23 SERTA PERFECT SLEEPER Cobalt Calm 14.5" MED PT mattress is soooo comfortable. I have a trashed spine and was looking for a new mattress and got this. It's the perfect Goldilocks mattress! I think I might have only turned once each of the nights since having it. I usually toss all night. For once I'm waking up without my back killing me!

[This review was collected as part of a promotion.] I chose this mattress base on the description since I chose the mattress online. I had been reading online to try to choose the best fit for me and its said that medium would be best for me since I'm overweight and a side sleeper but my husband is a back sleeper and also overweight. To my surprise when the mattress arrive, it was a lot firmer than I thought it would be. Like a lot firmer. The first night trying to sleep on the new mattress was hard, I tossed and turn all night. The second night was better but not by much. I looked online and read that it can take up to 1 month to break the bed in and for it to be more comfortable. It has been almost 3 weeks since I received the new mattress and I still think it's firm. This is not at all what I thought medium would be like. I sleep through the night now but I still waking up with some back pain because I don't think the mattress is supportive enough for me as a side sleeper. My husband said that he like the new mattress and that he has slept much better. Overall, I thought the mattress would be softer since it's a medium but I guess I will just have to get used to this mattress. Maybe if I'm really lucky, the mattress will break in even more and be more comfortable for me.

[This review was collected as part of a promotion.] This mattress is so wonderful. I've been having back pains and neck pains for quite some time now. When this mattress came I was so excited because I didn't have to wait for it to fluff up like most mattresses. It was already open and packaged. When we laid on this mattress i immediately noticed the difference and WOW! I instantly knew my current mattress was too soft. We literally threw it out. This mattress is not only gorgeous, but it's fine when laying down, but the pillow top is soft. Instant relief. It fit perfectly into our bedset and our sheets worked too. When it's hot this mattress stays cool and when it's too cold I notice we're still warm. This is the best thing ever created for the bed. Love love love!!

[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.

[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.] 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.
