Our dressers are built to provide maximum space for storage. The cabinet is built out of ¾ solid wood. The drawers have dovetailed corners with ¾ sides and a minimum ½ thick bottom. Drawers over 36 inches wide come with 100lb fully extendable slides. The back is usually ¼ furniture plywood this is only used to reduce the weight of the furniture to avoid the need of a forklift to move the piece.
