Perfect Sleeper. We're able to sleep at night. Very satisfied with with our back problems. Problem satisfied, very firm comfortable.❤️👌

I love the Serta Knox firm mattress! Even though it is firm, it is comfortable and I can sleep without any issues.

Seems to stay indented where I sleep. Didn’t think I would have that with such an expensive mattress. But seems to be comfortable.

Not too firm, not too soft, just right! In love with my new mattress. Highly recommend. It makes a difference!

These are the words of the wisest, smartest, and most beautiful person in the world: My Wife. Passes the wife test, passes my test.

I was looking for more support something not too hard and not too soft and I settled for the plush and it’s perfect!

Only had it 1 night and so far so good.

Great first nights sleep!

Comfortable and perfectly firm

Very firm. Looking forward to comfortable sleep.
