Design for sofabed. At upper right, partial plan gives dimensions of armrest and seat, while below at left, partial front elevation shows upholstery in red and describes mechanism by which either the back cushion folds down, or an upholstered armrest folds down (diagram inconclusive). At lower right, side elevation shows red upholstery again, provides dimensions, and indicates slatted armrest. Margins ruled in graphite. Inscribed with Deskey No. 8343.
