[This review was collected as part of a promotion.] WOW! After sleeping on this Serta Perfect Sleeper is amazing!! I have lower back problems with constant dull aches to shooting pain. After sleeping on the Cobalt Calm, I can happily say that it has helped reduce my lower back pain! The firmness of the mattress and continued support has helped minimize the amount of stress on my L5 disc. It is such a peaceful sleep, that I'd rather nap on my bed than the couch in the middle of the day! We are now looking to swap out the mattress in our guest room for a Serta Perfect Sleeper so that our family and friends can get the same type of sleep that we do when they spend the night! Definitely Serta for life!!

[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.] 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.

[This review was collected as part of a promotion.] I received my mattress a few days ago, and let's say it's an excellent mattress for my backache and desk hernia issues. It's very thick and rigid that it feels you are sleeping on the clouds or being carried. I have never felt this comfortable sleeping.

[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!

[This review was collected as part of a promotion.] This mattress has significantly improved my quality of sleep! I suffer from chronic lower back pain and this mattress has greatly reduced my lower back issues. I no longer wake up with back pain. I am a side sleeper and my body feels well supported, the memory foam allows my whole body to be supported. The middle of the mattress does not sag. The edges do not compress when getting in and out of bed. Excellent quality, well made. I am so happy with this mattress - a good night sleep is so valuable and this mattress has greatly improved my life! Trusted brand!

[This review was collected as part of a promotion.] This mattress was designed with a variety of different sleep types in mind. Love the pillow top on it as well. The color is wonderful as well. It was easy to carry and doesn't weight a bunch either. It was pretty tall so it will take the extra deep pocket sheets to cover it all.

[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 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 recently received my new Serta Perfect Sleeper Cobalt Calm 14.5" Firm mattress and I love it. The quality is far beyond my expectations and the comfort level is amazing. I have never had such a good nights rest before. I will be recommending this. Thank you Serta for making such a great product!
