[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.

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!!

This mattress starts out firm at first but after a few nights sleep is very comfortable. I normally sleep on my back and it’s very supportive of them mid to low back and cradled your body!

Having slept on our new Serta Perfect Sleeper X Hybrid Knox Plush Cal King for two nights has been wonderful. Supportive and comfortable for much needed good night sleep.

Love the firmness of this mattress. I’m a stomach sleeper and this provides me with the perfect amount of support for a great nights sleep. Also great for my husband who is a back sleeper. No more aches and pains upon wakening.

I'm a side sleeper and was looking for a firm mattress that would not make the pressure points in my shoulder and hips hurt. This hybrid mattress has been perfect for me!
