The present invention relates to a novel lifting and stowing device for a cover [ 1100 ] for a spa or tub [ 20 ]. Cover [ 1100 ] has a near piece [ 1110 ] a central piece [ 1130 ] and a far piece [ 1150 ] which fold and are stored in a compact position out of the way against the side of tub [ 20 ]. The invention [ 1000 ] employs a multi-link frame [ 1300 ] supporting the cover [ 1100 ] designed to lift and fold the cover pieces out of the way. Multi-link frame [ 1300 ] employs a main lift [ 1330 ] and a secondary lift [ 1350 ] of either side of a top edge [ 23 ] of tub [ 20 ]. Lifts [ 1330, 1350 ] retract in a scissor-like fashion to fold cover near piece [ 1110 ], central piece [ 1130 ] and far piece [ 1150 ] against each other. The cover lifting and stowing device [ 1000 ] lifts and folds cover [ 1100 ] inward toward the pivot point to move the cover weight closer to the pivot point reducing the required lifting torque.
