It is not sterdy and once you put files in it the draws fall off the track. I do not recommend this item. I am sorry I wasted my time to go to a location out of my way to purchase.
It was nice looking but I ended up taking it back the next day for a refund. The track guides inside of the cabinets are made of plastic and when the metal drawer rails are inserted into the cabinet they drawer rails would not stay inside the track guides. They would slip out of the plastic guides and not support any weight at all. I believe the track rails and guides should be both made out of metal.
