Solid wood and very sturdy once built. However, the instructions were confusing and unclear and while some parts had stickers labeled "front" they seemed to be on sideways and were not helpful. The diagrams were confusing, too, and I spent way too much time trying to figure out which direction something was supposed to go. I literally took apart and reassembled the side panels 6 times and then got the stand fully assembled, only to realize that the door drill holes were on the wrong side when I went to attach the doors. So mine has no doors for now, as I don't have the patience to rip it apart and reassemble it AGAIN. And I'm pretty good at building flatpack furniture, I built a dresser and nightstand and bookshelf earlier this year with zero problems. I just think the instructions needed to be clearer.
