The King Platform Storage Bed combines extra large drawers for plenty of storage space with a slat support system that requires only a mattress. Wood slats are positioned lengthwise to distribute body weight evenly, minimize the amount of motion transfer and take the place of a box-spring. Metal braces under the slats provide additional stability. Underneath are 6 large storage drawers (19″ depth) that run on smooth running metal drawer glides. Drawers open easily with finger pulls located at the bottom of drawer fronts and knobs have been eliminated to prevent bedclothes from catching. They are large enough to hold anything you need to store: linens, blankets, clothes, socks and even shoes are just a few ideas. Coordinate with the King Headboard and other Prepac bedroom furniture pieces. Overall bed height is 21″ if used with an 8″ thick mattress. This product is made from composite woods with plywood slats.
