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.

Abstract: An improved frame for a futon sofa/chair having a first base end and a second base end. The base ends have guide slots which engage guide posts, the guide posts are mounted to a back, which is pivotably attached to a seat. The improvement resides in providing backstops attached to the first base end and the second base end which further support the back of the sofa/chair when the back is upright and when the back is horizontal. In another embodiment of the invention, the frame additionally has a rear deck panel which is pivotably attached to the back and a pair of rear deck supports which are pivotably mounted to the rear deck panel and to the base ends. In a further preferred embodiment, the rear deck supports have deck segment supports which pivotably attach to the rear deck panels and base segment supports, which pivotably attach to the base. The rear deck supports and the rear base segment supports are in turn pivotably connected.
