Abstract
The convertible sofa-bed includes a base, a sliding and pivoting seat, a fold-out extension pivotally connected to the seat, and a fold-down seat back pivotally mounted to the base. The seat is pivotally connected to a pair of slides that ride on side rails mounted to the base, which allow the seat to be manually shifted between a horizontal seat position over base and a horizontal bed position spaced from the base. The seat is also pivotally connected to the slide by a ball joint that allows the seat to pivot upward so that the extension can be unfolded from beneath the seat. The ball joint connection between the slides and seat frame prevents the seat from binding when shifted between the seat position and the bed position even if the seat is not perfectly square with respect to the side rails as it is manually lifted and moved.
