I use Cabinet Grade Maple Plywood for the sides, back, and bottom of the drawers, and Select Pine for the Drawer Fronts. The drawers are on casters/wheels which are non marking, and also great on low knit type carpeting. The inner dimensions of each Storage Drawer is 39 inches x 36.5 inches and 7.5 inches deep. 
* IF BUYING DRAWERS WITHOUT THE PURCHASE OF A BED, THE DRAWERS MUST BE PICKED UP IN HIGH POINT, NORTH CAROLINA.
