Very supportive

[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 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.

[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.

Very firm but comfortably supports my spine after two surgeries. I go right to sleep without tossing and turning like I did with my previous mattress.

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.

[This review was collected as part of a promotion.] This durable mattress provides superior comfort and support while keeping maintenance at a minimum. The breathability is unmatched by the competition. Would recommend.

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!!

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 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!
