ABSTRACT:
A seating unit having lockable cushions. The seating unit includes a plurality of cushion guides for receiving the bottom and back cushions and a locking assembly which extends behind the backs of the cushions along the length of the frame for engaging the rear of each of the cushions. The locking assembly includes a locking bar having a plurality of slots which permit reversible lock pins located at the rear of the cushions to be received thereby. The locking bar is slidably received between the end cushion guide assemblies and is movable between a first locking position and a second unlocking position. A plunger-type lock located at one end of the locking bar prevents the locking bar from moving from its locking position. A biasing means located at the other end of the locking bar assists the release of the locking bar when the locking plunger is released. Accordingly, once the cushions are in place, engagement of the lock shifts the locking bar to its locking position thereby simultaneously engaging and locking the plurality of bottom and back cushions.
