  • Good Product
People buy box mattresses for a reason. It comes via Amazon to your front door! No dealing with delivery, set up people and it's inexpensive. Mattresses is firm so product description is accurate. If you add a cover it's even more so. Overall, good for the price.

  • Too soft
The mattress is comfortable for short term use. It’s a bit soft . Also the edge of bed all around is very soft and lacks stability. Not as thick as I would have thought. I did have to put a pillow topper that is about 5 inches wide which makes a difference. Opening box it came in was easy and it said it would inflate once plastic was cut open and to give it time. I waited 48 hours before using thinking it still needed to inflate but it was done really quick and that was as full it was going to get. Full size 12 inch mattress ... show more
