Purpose of a Bed Frame A bedframe does more than just raise your mattress off the floor. A bed frame fully supports your mattress and box spring without the assistance of a headboard and footboard. A bolt-on headboard may be attached to this bed frame, but such attachment is optional. Fits Twin, Full, and Queen Size Beds This bedframe will adjust to fit Twin, Full, and Queen Size box spring and mattress units; however, this bedframe does not include a center support which is needed with this bedframe for both the full and queen size applications. Therefore, if a full or queen size application is planned, it is recommended that a heavier duty bedframe be selected. Strong Sturdy Construction The side rails are constructed of 1 1/2" x 1 1/2" steel. Keyslot Crossarms Make assembly / selecting the chosen size easy and they lock securely in place. Locking Legs Creates a triple-thick steel layer at the corners for increased strength and rigidity. Standard Height The bedframe side rails are a standard 7 1/2" from the floor. Bolt-On Headboard Brackets This bedframe provides bolt-on connections for the headboard. The brackets are of heavy duty riveted construction and will fit virtually all bolt-on style headboards and footboards.
