So so

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

Perfect Sleep

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

Excellent mattress

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