This is a mattress for our granddaughters.  They love the mattress.  The memory foam with springs provides an ideal firmness to sleep on.  Their mom tells me that she sneeks in their room to take a nap while they are at school.  This was my first experience with a mattress-in-a-box packaging.  The box was easy to maneuver around and once opened the mattress expanded(just as the instructions stated).
