[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.] I received the SERTA PERFECT SLEEPER Cobalt Calm 14.5" FIRM PT a few weeks ago. I was a little concerned that it might be too firm but I can't sleep well on softer mattresses so I wanted to give it a try. Let me just say, I haven't slept better and I can't wait to crawl back in bed! It's firm but not hard. I have bad hips and this has even helped my hips to not feel sore in the morning after sleeping on my side all night. It stay cool throughout the whole night. That's big for me because I'ma very hot sleeper. I also love the fact it's anti microbial, so it will start feeling and smelling fresh longer than a typical mattress. Well done!

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!

[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'm very happy with the Serta Perfect Sleeper mattress. It is medium firm with a pillow top. I've found that medium firm is perfect for me, as it offers sturdy support, but is still very comfortable with the added pillow top. My partner prefers a firmer bed and I prefer a softer bed, and this mattress has been a perfect compromise for us. My partner suffers from back pain and has found this mattress to be very comfortable and supportive. On an aesthetic note, the dark cobalt shade is very pretty and the top of the mattress has a beautiful design. This is my first time trying a Serta mattress, and I cannot recommend it enough!

[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!!!

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.] 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 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.] This mattress is a game changer for those experiencing back or hip pain. The mattress we have is firm. It provides just enough support so that when you get up in the morning you're not sore. It's definitely a thicker mattress than what we had had in the past and had to order deeper pocket sheets. Not an issue because it's the best sleep we've had in years. Highly recommend Serta mattresses!
