This is very heavy duty solid wood!  The bed is sturdy and looks wonderful when it is all set up!  I strongly recommend taking your time reading directions and make sure you have plenty of room to lay all the materials out in groups according to letters... it is about an hour and a half for set up as you need to build it basically from scratch!  Also, my girls only had twin mattresses when they first got the beds... obviously, that cannot work well from the photos I submitted!!!
