[This review was collected as part of a promotion.] I need to upgrade my son's twin mattress and this queen size mattress is great! It is thick, and firm but not too firm. My son loves it! You do need deep pocket fitted sheets for it though - but that just shows how nice and thick the mattress is. I highly recommend this mattress!

[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.

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.

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 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.] My wife and I have had this mattress for about a month and have found it very comfortable. We opted for the medium one and it is just right. I tend to be too warm when sleeping and I havent noticed that since using this mattress.

[This review was collected as part of a promotion.] The Serta Perfect Sleeper, Medium Pillow Top is perfect if you are in between wanting a firm or soft mattress. My husband likes a firm mattress and I prefer soft. This is a perfect solution to our preferences! The coils are nice for support and offered a wonderful nights sleep. This mattress is durable and I think we will get many years out of it.

[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.] 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.
