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!

Firm and comfortable

The mattress is very firm, which I at first was unhappy about. However now, after several months, I am very glad I chose it.
