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.

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!

Excellent mattress

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

Adjustable bed

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