No more back aches

Very supportive

good Support for my back

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.

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

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

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

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

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

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