This is a very well constructed and very nice looking file cabinet. It is constructed of wood and plywood...there is no particle board. This would easily be a five star review had the only put a piece of trim inside the front of the drawers. This trim would have accomplished two things 1. It would have covered the plywood edge that shows as soon as you open the drawer and 2. It would keep that first file folder from falling over the edge. It is the same issue in the rear of the file cabinet. To resolve these issues I simply put an empty folder in the front and rear of each of the drawers so the empty folders keep the active folders from going over the edge. Despite this flaw I still don’t regret my purchase. This is a beautiful piece of furniture and goes great even in our formal dining room.
