An automated sofa bed includes the usual elements and structure of a conventional sofa, an extensible articulated bed frame, and power means to extend and retract the frame. The basic sofa includes a rigid, stationary frame adapted to receive conventional seating pillows and formed with a cavity to receive the folded articulated bed frame. The bed frame comprises a plurality of generally rectangular sections pivotally connected to each other on traverse axes and foldable into a relatively compact package storable within the cavity in the rigid stationary frame, and extendable into a relatively horizontal arrangement suitable for use as a bed. At least one section of the bed frame is mounted on pivotal links to control its path of movement, and power means is applied through floating power links to the bed frame to move it between its extended and stored positions. The preferred form of power means includes cable means connected to the floating power links and an electric motor to drive the cable.
