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

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

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

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

My sister seems to be comfortable and sleeps well through the night. No more saggy mattress she wakes up with a smile on her face.

Have had one night only so far and we are very pleased. Slept very well! Just the right level of firmness for us.

I like the bed but unhappy that I cannot use my head board and it is difficult to keep the top sheet secured.

Excellent so far and comfy.

Looks really solid and durable. My son will love it!

Comfy and supportive mattress 👍
