Perfect!

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

Impressions permanent in less than two weeks

The mattress already has divots or impressions from where we sleep in less than two weeks. We are not overweight.

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

Excellent mattress

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