This did NOT come with a solid platform for the mattress to set on.. it came with PLANKS..  ?? The frame is made of Pressboard ( not impressed) and it's construction allows for your ankles to get beat up when getting in the bed. It is VERY low in height.. the ONLY reason we kept this was we just moved in to a new home and did not want to sleep on the floor while searching for and shipping a new bed. We will be selling in a garage sale as we have a MUCH BETTER frame now... save your money unless you are only needing a guest bed frame that gets used 3 times a year..
