I ordered this mattress to convert my daughter's crib to a full size bed and I wanted something that was going to be comfortable and would like to last till the teen years. This mattress is very nice. Very soft yet not so soft that you sink to far into the mattress. The mattress set however is a bit tall. And with the crib frame being a little tall as well it made for an extremely tall bed. We had to remove the box spring and store it while placing the mattress on a plywood base till my daughter is a little older and I wouldn't worry about her falling off while trying to get off and on the bed. Even on the plywood patform is still is very comfortable.
