It came in many boxes, delivered on different days, with many different sets of instructions.  I quit using the instructions after a while.It is very sturdy and heavy.  You can picture someone trying to stack a full size bed on top of another full size bed...get some help.  The drawers are large and roll on the floor.  My kids love it!Would be 5 stars if the instructions were better, shipment all came on the same day, and the drawers had a track.
