Firm and supportive

Very supportive

[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!!

Once I lay down to sleep, I fall to sleep immediately and sleep the entire night. It is very comfortable and no aches or pains. I am totally happy and satisfied with it

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 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.

[This review was collected as part of a promotion.] This mattress is super comfortable and gives us all the support we need, have seen a difference waking up with less body ache and strained back muscles.

This mattress is so comfortable! It's firm but not too firm. I added my own pillow top and it feels like sleeping on a cloud. I'm a back sleeper and feel like this mattress has improved my sleep quality.
