This cabinet is made of thin gage steel but seems sturdy enough for infrequently accessing files. It has raw sheet metal seams exposed on the underside which are a great risk for use in a room with hardwood floors. The frame on the underside is not amenable to attaching glides so I laid a piece of particle board under mine. One of my handles had a screw or tap broken off in its screw hole preventing me from attaching it to the drawer. A week after contacting customer service a replacement hasn't arrived yet. Be careful to only open 1 drawer at a time or the cabinet will tip forward. The cabinet has an open bottom so I can't lay counterweights in it. The lock is really chintzy and can be easily defeated with a screwdriver or butter knife. It'll do ok to hold my files until next year's tax time but I wouldn't recommend it for a home office where files must be accessed multiple times a day.
Won't ever buy a filing cabinet from them again. You open the drawer and it falls. Fixing to get me an old government filing cabinet one that the drawer doesn't fall when opening.
