[This review was collected as part of a promotion.] I am so, so happy I have this mattress. This thing is AMAZINGLY comfortable. Of course, mattress firmness is a personal preference so I can't say it'll work for everyone but this mattress is the perfect blend of firm and plush with the added benefit of cooling. It's not your typical mattress - the top layer is cooling and plush and my body feels supported all over as I sleep. It is so thick that I was afraid my regular bed sheets might not fit but that wasn't a problem at all, thankfully. You get what you pay for and this mattress is worth it's weight in gold! I would have given it more stars if I could.

[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 had it for a week and its just wonderful, my back and body thank me everyday. Very comfortable. I used o have back pain and feel tired every morning. Now that I have used this mattress I feel more rested and no back pain. The quality of the mattress is always great, Serta doesn't disappoint.

It was time for a new mattress, so we tried a hybrid, but found it not comfy enough for side sleepers. So after a bit more research, we decided to go with a Serta Perfect Sleeper, since we had previously purchased a full size 10+ years ago and it's still comfortable! This queen size of the same make is very comfortable. Thankful for a good night's rest again, and no sore shoulders!

I'm enjoying this mattress so far. The first week was rough to fall asleep simply because with each twitch, I was basking in just how good it feels. I don't know if the top should develop a sinking indentation (close up pic) but it isn't bothersome yet but it is in fact noticeable laying on it. I never owned a mattress in this price range know if this is normal or not. I will definitely keep my eye on it & the calendar as I'm still in the trial period. The registration with the QR code was a pleasure, sure was easy and I took a screenshot of the confirmation just for added measure. Hopefully someone from Serta will read this and reach out to me about the developing indentation.

[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.] 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.] 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.] This is the first Serta I have owned. It's 14.5" so has a good amount of thickness to it and we have a queen. My husband is a back or stomach sleeper. He has broad shoulders and unfortunately snores. Some beds make his shoulders hurt if not enough padding. I am a side sleeper. This mattress has been great for us over the last couple weeks. The many coils help distribute movement to give yet a restful sleep if your partner moves around. One big plus to this mattress is it's not pretty much every night now that my husband snores. I am getting more of a restful sleep. With the combination of this mattress and pillow, my husband's shoulders have been comfortable. I plan to purchase a Serta in the future too.

[This review was collected as part of a promotion.] This is the best most comfortable mattress that I've ever owned. Relaxing, feels good to your back, You lay down, you feel very very satisfied! My sleep every night has been very peaceful and relaxing because of this mattress, I can certainly recommend this to anyone looking for a new mattress!
