A chair apparatus includes a base frame, an intermediate frame coupled to the base frame, and a resident support frame including a back section, a seat section, and a leg section pivotably coupled to the base frame and the intermediate frame by a plurality of links to permit the support frame to move from a chair position to a flat position. The apparatus also includes a cylinder and piston pivotably coupled between the intermediate frame and the base frame to hold the intermediate frame in a selected position relative to the base frame, a first actuator coupled to the cylinder to release the piston and permit tilting movement of the intermediate frame relative to the base frame to recline the support frame relative to the base frame, a spring assist coupled between the intermediate frame and the support frame, a locking mechanism coupled between the base frame and the support frame to hold the support frame in a desired position relative to the base frame, and a second actuator coupled to the locking mechanism to release the locking mechanism and permit movement of the support frame relative to the base.
