[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.] 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.] 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 Serta mattress is the best mattress I've ever had. It's so comfortable and soft, yet firm at the same time. It's absolutely perfect. Extra thick and cushiony and guaranteed to give you the best night's rest you've had in a long time. I'm finally sleeping like a teenager again!

[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.] This mattress is just what I needed. It's firm but still super comfortable and I'm no longer waking up with a sore back that alone is worth it. You can definitely tell this mattress is built with quality material's definitely a high end mattress.

[This review was collected as part of a promotion.] The support on this Serta Perfect sleeper firm mattress has been great for me and my husband. It really helps that it has the pillow top to give the bed a little more cushion and softness. It's great because neither of us sink to the middle of the bed. I've always had Serta mattresses and they hold up very very well. I am looking forward to the many years to come with my new mattress!

[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 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.] 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!!
