My son loves it

[This review was collected as part of a promotion.] We put this serta mattress in my son's room and he loves sleeping in it. It's really comfortable for us as well for those nights he wants us sleeping with him. My husband and I don't wake with any back pain like we did with his old mattress. 10/10 would recommend

Firm support, yet comfortable

[This review was collected as part of a promotion.] This mattress is firm and provides strong support. We lay it on the ground to sleep to nurse our newborn. You can lie down or getup without rocking it or disturbing each other. High quality mattress and well constructed.

Supportive and so comfortable

[This review was collected as part of a promotion.] This is the most comfortable mattress that I've ever owned! I've bought all sorts of toppers in the past to try to make our old mattresses more comfortable but this one has been amazing straight from the box! It didn't need to air out and had zero off gassing smells. I usually feel unsupported on my lower back but this pillow top really fills out your curves and supports everywhere. The floral design is very cute, I do worry that it might pill but haven't had any issues yet.

Definitely LOVE!!!

[This review was collected as part of a promotion.] At first I was skeptical to receive a mattress to review however I am truly blown away by the quality and comfortability! I went from total memory foam to this and it has truly made a different in the support on my back! I can also tell the different with their cooling technology! I feel blessed and extremely grateful for this opportunity!

Firm and hefty!

[This review was collected as part of a promotion.] The Perfect SIeeper Quilted Hybrid was aesthetically, a very clean beautiful mattress with quite a bit of thickness and heft, which made setting it up a bit challenging without assistance. The weight does add to the sense of durability and sturdiness. I was pleasantly surprised to find no odor, which is often an issue with newer mattresses. Most notably though, the mattress is quite firm, which is the style I selected. It's exactly as advertised, very firm. There is little cushion or give but provides great support. I would not recommend this mattress if someone wants to "sleep on a cloud" but rather, would be ideal for those needing extra back support. For anyone looking for a firm mattress that feels built to last, this one would be a great choice.

Great mattress with wonderful support!

[This review was collected as part of a promotion.] This Serta Perfect Sleeper Quilted Hybrid 24 Knox FM TT Queen mattress is wonderful! It’s comfortable and has improved my sleep quality immensely! I no longer wake up with back pain and it keeps me cool and I do not wake up in the middle of the night sweaty anymore either! This mattress has been a godsend and I love the fact that it’s dark and not the typical white like other mattresses I’ve owned. I really love this mattress and have been recommending it to everyone I know! It’s honestly the best mattress I’ve ever had!

Great night sleep on this firm, pleasant cooling effect, high quality material and beautiful design pattern

[This review was collected as part of a promotion.] Great mattress! I was very excited to finally get a new mattress and I had such a great night of sleep after sleeping on this Serta one. My previous mattress was softer, and I had been waking up with some back pain, but this mattress is firm and helps a lot with my back and hips not sinking in as I sleep. It has a pleasant cooling effect so I didn’t feel overheated at night, and I love that it’s thicker as I like to sleep higher up off the ground since I am tall. It was such a shame to have to cover up the mattress with my bedding as I loved the design and dark blue and white color patterns. It also has helpful handles on the side so you can adjust it as needed on your bedframe. It’s on the heavier side, but most of my mattresses in the past have been heavy as well so I didn’t mind that. I prefer a heavier mattress, so it feels more sturdy when I am on the bed. I would definitely recommend this to anyone looking for a firmer high quality mattress!

Best Sleep Ever

We got a new mattress and after much deliberation, went with a Serta. We have no more back or hip pain when we wake up in the morning, it has great support, and I haven’t slept this great in years. Another thing that impressed me was the attention to aesthetics; the embroidered flowers on the mattress top are lovely. Thank you Serta!

Bad quality

I just started sleeping on this mattress and it has a horrible bubble in the middle. This is the cool calming queen mattress. It's a replacement for a different mattress from serta and it only lasted 6 months before the sides started caving in. I will never buy a serta mattress again.

It offers everything I need

[This review was collected as part of a promotion.] This mattress strikes the perfect balance between firmness and softness. The hybrid design combines the support of coils with the plush comfort of memory foam. It’s firm enough to provide excellent support for my back, which is crucial after long days of household chores, yet soft enough to feel like I’m sinking into a cloud every night. One of my biggest concerns with mattresses has always been overheating during the night, but the Perfect Sleeper has really impressed me. The quilted top layer seems to do a great job of regulating temperature, keeping me cool. The build quality of this mattress is outstanding. It feels sturdy and well-made, and after several weeks of use, there’s no sign of sagging or wear. I believe this mattress will last for many years, which is a relief because I definitely don’t want to go through the hassle of mattress shopping again anytime soon! One unexpected bonus is the excellent edge support. I can sit on the edge of the bed without feeling like I’m going to slide off, which is great for those moments when I need to slip out of bed quietly without waking anyone else. Overall, it has been a wonderful addition to our home. It offers everything I need in a mattress: comfort, support, durability, and a cool sleeping experience
