[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 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.] 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.] I got the Serta Perfect sleeper for my back issues and so far I absolutely love it. It has the perfect firmness and with the pillowtop and it doesn't make it too fluffy or too soft. The mattress itself is well built the material is strong and sturdy making this mattress a great quality product. I highly recommend this to anyone with back issues or to those that like a firm mattress.

[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.] 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.] 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.] I am currently laying on my new serta mattress and let me tell you it is simply amazing. The mattress is firm yet soft. It is not bouncy at all. There is no sound when moving around. It is also pretty tall, I am a short person and I have the mattress on a steel boxspring and I kinda have to hop up to get on. This is the best mattress I have ever slept on, reminds me of when I go to a nice hotel and get a good nights sleep. Highly recommend for all!

We had a nectar mattress for the past 10 years, it was nice but wanted to support of an inner structure with the comfort of a memory foam. This was the best of both worlds getting the Serta hybrid. The Med firm with pillow top is perfect. I get great sleep, I am a side sleeper, wife is a back sleeper. Both are extremely comfortable.

[This review was collected as part of a promotion.] The Serta perfect sleeper mattress is amazing!!! It is so soft and makes sleeping so much nicer! It is very light and easy to move around! It fit perfectly on my bed frame with no issues! It is my favorite place to be.
