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.

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!

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.

Have you ever wanted your bed to give you a hug?

[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.

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.
