Seems pretty sturdy, but it is all pressed wood. Biggest problem that we haven't found a solution to is the drawers are getting caught halfway out, sometimes refusing to close. It seems like a hole in the metal track piece is acting as a landing spot for the roller. We are hoping to find a way to essentially fill that hole and smooth out the drawer movement.

Update, by screwing in some of the screws along the track in a bit farther, and switching some shelves around, the drawers are moving more smoothly now. Added a star.
