ABSTRACT:
The present invention is for a futon frame which, in combination with a futon, will serve as a sofa or couch when in the closed position and a bed when in the open position. The futon frame has a base having a first end with a first base end slot and a second end with a second base end slot. A back is provided which has a first back side member and a second back side member. A first back pivot pin attaches to the first back side member and a second back pivot pin attaches to the second back side member, with the first back pivot pin slidably engaging the first base end slot while the second back pivot pin slidably engages the second base end slot. Preferably, the base end slots define a serpentine path. A first back support pivotably attaches to the first back side member and the base while a second back support pivotably attaches to the second back side member and the base. A seat having a first seat side member and a second seat side member pivotally attaches to the back. A first seat support pivotably attaches to the first seat side member and to the base while a second seat support pivotably attaches to the second seat side member and to the base. Preferably, the seat is fitted with supplemental support legs which are automatically concealed within the frame during closing. The use of serpentine base end slots reduces the forces one needs to apply in opening and closing the futon frame.
