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.

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

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!
