One embodiment of the futon frame has a base having a pair of base end serpentine slots. A back is provided which has a pair of back pivot pins which slidably engage the base end serpentine slots. A pair of back supports pivotably attach to the back and the base. A seat is pivotably attached to the back and a pair of seat supports pivotably attach to the seat and the base. Preferably, the seat is fitted with supplemental support legs which are automatically concealed within the frame during closing. In a second embodiment an additional pair of back pivot pins are provided which, in combination with an additional pair of base end serpentine slots, replace the back supports.
