An adjustable folding bed frame including a plurality of longitudinal beams spaced apart and parallel to each other. Each longitudinal beam is formed by a pair of longitudinal bars that are pivotally connected together. The bed frame also includes a plurality of transverse beams spaced apart and parallel to each other. Each transverse beam is formed by a pair of transverse bars that are pivotally connected together. Each transverse bar has a first sliding member slidingly coupled with a second sliding member for adjusting the bed frame to predetermined widths. The bed frame also includes legs connected to a corresponding lower side of each longitudinal bar free end. The longitudinal and transverse bars are coupled together to form a generally rectangular frame when the bed frame is in an open configuration, and are folded adjacent and parallel to each other when the bed frame is in a folded configuration.
