The present invention relates to the technical field of folding couches, and discloses a folding couch including: a first bed frame, a second bed frame, a first support assembly and a second support assembly, wherein the first bed frame and the second bed frame are hinged via a hinge, the first support assembly is used for supporting the first bed frame, and the second support assembly is used for supporting the second bed frame. The present invention is convenient for folding, stowing and transporting a couch, which may reduce transportation costs.

A seat assembly includes independently rotatable and reclinable seats. The seats have back support sections that can be rotated between a sofa position and a compact position as well as the sofa position and a reclined position. The seats can further include leg rests that are movable between a lowered position and a raised position.

A convertible chair-bed is provided, including: a fixed bed frame and a movable bed frame; a head frame body, a hip frame body, a leg frame body, and a tail frame body that are rotatably connected in sequence, wherein the head frame body and the hip frame body are both lapped on the movable bed frame; a rear extension rod fixedly arranged at a bottom of the hip frame body; a diagonal stay, wherein two ends of the diagonal stay are respectively rotatably connected to a front end of the tail frame body and the fixed bed frame; a rotating stand rotatably mounted on the movable bed frame; a first telescopic rod; and a second telescopic rod, wherein two ends of the second telescopic rod are respectively rotatably connected to the head frame body and the movable bed frame.

The invention discloses a sofa seat frame, a sofa base assembly, a sofa and a sofa production and assembly process, the sofa seat frame comprises two cross beams arranged at intervals and two longitudinal beams connecting the two cross beams, wherein a plurality of supporting elastic pieces are arranged between the two cross beams; and each longitudinal beam comprises a first supporting plate for supporting a seat cushion and a first side plate arranged at one side of the lower part of the first supporting plate and used for being detachably connected with sofa fabric on the seat cushion. In the sofa seat frame provided by the invention, when the seat cushion is placed on the supporting elastic pieces, the first supporting plates can give a certain supporting force to the seat cushion, so as to improve the sitting comfort of users.

The folding couch including: a first bed frame, a second bed frame, a first support assembly and a second support assembly, wherein the first bed frame and the second bed frame are hinged via a hinge, the first support assembly is used for supporting the first bed frame, and the second support assembly is used for supporting the second bed frame. The first support assembly and the second support assembly are foldable and stowable to the first bed frame and the second bed frame.

An adjustable seat system transformable from a first, bench seat orientation to a second, lay-flat bed orientation, to a third, raised bed orientation, to a lounge orientation there between. The system includes a seat, a seat back, a foot rest with a foot rest cushion, and a bed cushion stored behind the seat back when in the first, bench seat orientation. The foot rest can be independently raised and lowered as desired. When the bed cushion is moved from a stored position to a horizontal position, the seat, seat back, and foot rest elements are moved away from the bed cushion and can be oriented into a horizontal position to form the second, lay-flat bed orientation. A pair of adjustable seat systems can be deployed together and separately and autonomously controlled. The pair of adjustable seat systems can be moved apart and rotated to be oriented about an optional dinette.

An extended leg mechanism includes a first leg connecting rod and a second leg connecting rod, where the first leg connecting rod, a third leg connecting rod, the second leg connecting rod and a fourth leg connecting rod are pivotally connected in sequence; the third and fourth leg connecting rods are pivotally connected to an identical first footrest assembly; the first footrest assembly includes a vertical plate pivotally connected to the third and fourth leg connecting rods, and a top portion of the vertical plate is provided with a mounting plate, where the vertical plate is pivotally connected to first and second footrest connecting rods, the other end of the first and second footrest connecting rods is pivotally connected to an identical second footrest assembly, and the second footrest assembly, a third footrest connecting rod and the fourth leg connecting rod are pivotally connected in sequence.
