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.

[This review was collected as part of a promotion.] The most comfortable bed I have ever slept on in my life. It’s cooling too so it’s perfect for the summer when it’s too hot to sleep. Breathes easy and supports my body weight and heavy dogs with me.

[This review was collected as part of a promotion.] This bed is comfortable and not too big or small. It's not lumpy or flat. I get really good sleep with this mattress. It holds its shape, even when it's adjusting to my body. It's has a nice pattern on it and it doesn't leave me feeling too hot or cold.

[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!

[This review was collected as part of a promotion.] ABSOLUTELY AMAZING! I can't believe I received a mattress, an extremely comfortable one at that! It adds so much to the room. The height is great & completes the room. The design on the mattress is very intricate. Good support, durability, and comfort. It's soft yet firm. Love this mattress!

[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.

[This review was collected as part of a promotion.] I was so excited to receive this mattress! This is the most comfortable bed that I have slept on. Everything from the cooling technology to the perfect balance of firmness to plush. I’ve never had any discomfort from sleeping and I am a side sleeper. I would recommend this mattress to anyone in the market for something new that has great cooling technology and molds perfectly to make a great nights sleep!

[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.

[This review was collected as part of a promotion.] This bed was put into our guest room and it might be more comfortable than my bed. With the right mattress protector, the mattress is surprisingly cooling and cozy in both hot and cold weather! The mattress has the perfect balance of plushness and support for your body. I would recommend to anyone looking for a new mattress.

[This review was collected as part of a promotion.] I have spent a full month sleeping on this mattress. I love it! I am a bit of a princess and a pea when it comes to mattresses. Most importantly for me, I am a woman who wakes up hot in the middle of the night. Not sweaty but just hot, not in a snuggly way but an uncomfortable way. I have not had that issue at all with this mattress. It conforms and cradles your curves if you are a side sleeper and it is a very tall mattress which I like. For reference, my previous mattress was a tempurpedic so I was worried about it being too soft but while the top is thick and plus, it has plenty of support. Very pleased with this mattress!
