This mattress is firm and supportive exact comfort for me with a touch of softness like a pillow top. I just love it.

Our new Serta mattress and box springs are very comfortable and supportive (for my bad back). This mattress is very well made.

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.

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.

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

Comforting for a very relaxing sleep.

Comfortable and supportive mattress

Love our new mattress! Firm and supportive, providing a good night’s rest.

Enjoying this new mattress!
