Firm but comfy

It’s a really nice mattress we just have to get use to the firmness!

High quality good performance

[This review was collected as part of a promotion.] This Matress has been really good with my back. It's comfortable and you get good sleep at night. The hybrid technology keeps my body cool and it's nice to feel firmness along with comfort.

Finally; no pain

Was having severe back; hip and shoulder pain. Slept on another bed on vacation and realized I needed to get a new mattress!! It’s amazing how much better I feel!!

Comfy Cozy

[This review was collected as part of a promotion.] This is a great mattress. It's tall, so if you have a tall frame you might want to get a new one. I love it. It's comfortable. I do think it could use a little more support but I love it.
