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.

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

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.

So far it’s comfy

No more back aches

Great night's sleep!

Firm and supportive!!
