[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.

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.

This mattress is, “da’ bomb!” Folks, if you think I’m fibbin’, get one! It seems to re-align sleeping posture, I miss work, on purpose to stay on this mattress! I removed the bedding to get model number for warranty- 10 years limited.

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!

[This review was collected as part of a promotion.] This hybrid mattress is perfect for our guest room. It is comfortable, durable, and breathable. It is a firm mattress, but it doesn't feel too hard, and the support it provides is great.

[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.

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!!

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!
