I would describe as medium firm, used on slat bed, no box spring required which helps the price point. I'm impressed and as a designer, bought many mattresses. This mattress would work well on an adjustable bed too! I opted for a gel topper for extra comfort. My queen size bedding worked fine on 12" mattress w/topper. I chose a 12inch deep full size for additional space.

This is perfect. The packaging was thorough. It shipped from Georgia via FedEx and came a week sooner than expected which fell in line with the setting up of our son's bunk bed. It expanded to nearly the size of a queen. We brought "full" sheets and it was snug.
