Abstract
Abstract A sectioned cushion couch used as a chair when folded and as a chaise longue when unfolded. The couch comprises a unitary seat and back section to which is serially hinged one or more additional sections capable of being folded underneath the unitary section to form the base of a chair. Conversely, the additional base section or sections may be unfolded from chair supporting position to extend the length of the seat and back section and thereby form a chaise longue. The cushion sections are preferably composed of foam cushioning compositions such as urethane, neopreme and latex. The seating and backrest area of the chair adjacent the occupant is cushioned with a relatively light density weight foam to afford seating comfort, while more remote portions of the seat and backrest section and the entire base section or sections are cushioned with a denser foam composition to provide the necessary rigidity and strength.

Claim 1
Independent Claim
221 words
A cushion couch comprising: a. a unitary seat and backrest cushion (2); b. a second cushion (8) having its upper surface interfacially engageable with the bottom surface of said first cushion (2) to thereby form a cushioned chair, the front faces of said cushions lying substantially in an upwardly extending plane transversely intersecting said interfacial cushion surface; c. hinge means (16) connecting said cushions (2, 8) at said intersection (18) whereby the second cushion (8) may be swung from its interfacial position to a position extending laterally from the front face of the first cushion (2); d. a bottom cushion (11) having its upper surface interfacially engageable with the bottom surface of said second cushion (8), the back faces of said first, second and bottom cushions lying substantially in a second upwardly extending plane transversely intersecting said first and second interfacial cushion surfaces; e. a second hinge means (16) connecting said second and bottom cushions (8, 11) at the intersection (18) of said second interfacial surface with said second plane whereby said bottom cushion may be swung to a position laterally alined with said second cushion; and f. means (17) releasably connecting said first hinge means (16) to the front portion of said bottom cushion (11) to thereby fasten said second and bottom cushions (8, 11) in said interfacially engaging position.
