Very supportive

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 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.

[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.

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!

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

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.
