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.

grnlight

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

Big bed, extra supportive

Large bed, supportive mattress, taking a bit of time getting used to it. Too soon to say.
