Super comfy

[This review was collected as part of a promotion.] I couldn’t be happier with it! From the moment I unboxed it, I could tell it was a high-quality mattress. The hybrid design combines the best of both worlds with a comfortable foam layer and supportive innerspring coils, making it incredibly cozy yet supportive. The medium-firm feel is perfect – it strikes just the right balance between softness and support, making it ideal for a restful night’s sleep.

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!

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!

Comfortable

[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!
