The  specifications say the shelves are "metal", but that is false.  The shelves are made out of particle board.  There is some minor scuffing on the shelves due to movement during shipping, they could do a better job of packaging the shelves.  Aside from that, assembly was easy and the unit seems sturdy.  Best of all it sits nice and level with no wobbling on my tile floor.  The feet screw in so if your floor is slightly off level adjusting the feet could likely cure that.
