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

Great for the price

[This review was collected as part of a promotion.] I recently got the Perfect Sleeper Quilted Hybrid 24 Knox FM TT Queen size mattress, and it's been a game changer for my sleep. The hybrid design offers the perfect balance of support and comfort. The firm feel is ideal for my back, yet the quilted top adds a layer of softness that makes it very cozy. I wake up without any aches, and I notice an improvement in my overall sleep quality. It’s also well-made and feels durable. Overall, a fantastic mattress that delivers both comfort and support for a restful night's sleep!

Sleep Cool and Comfortable

[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!

Disappointing

Already showing body imprints. Not really "cool" sleeping. It's just ok.

Getting to know each other

First few nights was a little stiff. But now settling in and super comfortable.
