Abstract

An upholstered foldable furniture system having a first assembled configuration for seating and a second unassembled configuration for storage and shipping. The furniture system has a horizontal seat support frame having front and rear support frame members, spaced left and right side support frame members, a back member having a bottom back member rotatably secured to the rear support frame member and left and right back side support members. The back member is rotatable between a position substantially parallel to the horizontal seat support frame and an angle of not less than 90° with respect to the horizontal seat support frame. Left and right arm members are provided, each having a rear arm frame and a lower arm frame. The left and right lower arm frames are secured to the left and right side support frame members respectively. The furniture system also provides left and right latch assemblies. When the furniture system is in the first assembled configuration for seating, the back member is in a substantially vertical position, the left and right arm members are in substantially vertically upward positions, and the left and right latch assemblies are latched. When the furniture system is in the second unassembled configuration for storage and shipping, the back member is in a substantially horizontal position, and the left and right latch assemblies are unlatched.
