For the price you can't go wrong. The description says the slats are at 5.5" but I'm not sure where they are measuring from. They are about 9" from the ground. I'm using the bed for my toddler (big girl bed) without a box spring and the height is perfect. She can get in and out without assistance at 2.5yrs old. Took about 45 minutes for assembly, comes in two boxes.
