[This review was collected as part of a promotion.] This serta mattress is nice but I will say if you don't like a real firm mattress this isn't for you. The design on it is nice and the pillow top is nice to. It definitely needs a low profile set up too.

[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.] This is an amazing mattress! The extra pillow top is where the manic is at. I seriously might upgrade to a king just because it is that comfortable! Serta is an amazing brand that goes above and beyond for their customer.

[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.] 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 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.] This is a fantastic mattress, and I know exactly why it is named “Perfect Sleeper”. Since sleeping on this new mattress, I have had some of the best sleep I've ever had. The mattress is the perfect combination of softness and firmness. The thick, plush pillow top feels like a comfy cloud but with the firm support, my body doesn't sink and is gently supported from all angles. The mattress has a nice cooling aspect and doesn't make me feel too warm. Fabric is sleek and smooth as well. Even the color scheme and design on this mattress look high end and it's a shame it gets covered with a sheet. Sleeping on the Serra Perfect Sleeper, I have never woken up stiff or sore. Mattress height is quite high, at 14 inches so it is important to note that some sheets won't fit all the way around and I needed to use deep pocket sheets. This is a quality made mattress with a lot of advanced comfort features. I am very happy with it.

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.] 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.

[This review was collected as part of a promotion.] This PS23 SERTA PERFECT SLEEPER Cobalt Calm 14.5" MED PT is probably the best mattress I've ever slept on. I LOVE it! Definitely recommend to everyone! So comfy and great quality! Love love love it!!!
