[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!

[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.] I bought PS23 SERTA PERFECT SLEEPER Cobalt Calm 14.5" MED PT for our new mattress and it truely is amazing. I love that it's not to soft or hard it's just right. It is firm enough to keep me from rolling yet soft enough to let me sink in. It is a game changer with sleeping.

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.

We went to the local dealer for a replacement and we're talked out of a pillow top. Sales clerk suggested this one because over time the pillow top seems tiger moved around. We are waking up with backaches so we will be trying to get this swapped out.

[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 got the Serta Perfect sleeper for my back issues and so far I absolutely love it. It has the perfect firmness and with the pillowtop and it doesn't make it too fluffy or too soft. The mattress itself is well built the material is strong and sturdy making this mattress a great quality product. I highly recommend this to anyone with back issues or to those that like a firm mattress.
