A lower chair for supporting an upper chair on which a user sits. The lower chair including a base, a swivel mechanism supported by the base and defining a vertical swivel axis, and a four-bar linkage mounted to the swivel mechanism for rotation about the swivel axis. The four-bar linkage includes a coupler link that moves about a coupler curve. The lower chair also includes a column having a lower end affixed to the coupler link for movement of the lower end along the coupler curve. The column defines a column axis and is adapted to support the upper chair.

A spring mechanism for a chair or a stool includes a base mount connected to a base and a seat mount connected to a seat. Two swing arms are arranged above one another. The two swing arms include a lower swing arm and an upper swing arm. Each of the two swing arms is pivotally connected to the seat mount and pivotally connected to the base mount. A spring is provided and arranged to generate an upwardly directed force onto the seat.

A rotary hanging chair comprises a cushion, a support frame and a base assembly. The cushion has two ends connected to an upper end of the support frame and is able to swing forwards and backwards with respect to the support frame. A bottom of the support frame is connected to the base assembly and is able to rotate within 360° with respect to the base assembly. The entire rotary hanging chair comprises three detachable parts, thus being simple and practical in structure, not only can swing forwards and backwards like a traditional hanging chair, but also can rotate within 360° to change the direction freely to meet the requirement for switching the view angle, and is small in size, easy to carry and capable of being used both indoors and outdoors.

A foldable hanging basket includes a hanger and a hanging basket body. The hanging basket body is suspended on the hanger by a sling chain. The hanging basket body comprises a hanging basket chair and a lifting frame assembly. The lifting frame assembly comprises a main frame and several auxiliary frames. The main frame and the several auxiliary frames are arranged in intervals, a lower border of the main frame is hinged and matched with a front border of the hanging basket chair, and two ends of each of the several auxiliary frames are successively hinged and matched with borders on both sides of the hanging basket chair. The main frame and the auxiliary frames may be rotated and folded in a plane of the hanging basket chair.

A chair includes a movable part including a seat on which a user sits, a supporting part configured to support the movable part in such a way that the movable part can be moved to the right and to the left; and a restoration unit, which is a biasing member configured to bias the movable part toward the neutral position in the right and the left. The supporting part supports the movable part in such a way that the movable part descends as the movable part is away from the neutral position.

A reciprocating seating unit includes: a base; a frame including a generally horizontal seat and opposed arms; a backrest; a reciprocating unit attached to the base, the reciprocating unit configured to permit reciprocating longitudinal movement of the frame and backrest relative to the base; and a reclining mechanism attached to the reciprocating unit, the frame and the backrest. The reclining mechanism includes pivotally interconnected links and is configured to move the backrest between an upright position, wherein the backrest takes a first backrest angle relative to the underlying surface and the frame is positioned relative to the base in a first location, and a reclining position, wherein the backrest takes a second backrest angle that is shallower than the first backrest angle, and the frame is positioned relative to the base in a second location that is at least 3 inches in front of the first location.

A hanging chair includes a collapsible spreader bar that reduces the size of the product when in a disassembled configuration. The hanging chair includes a flexible seating portion having first and second side edges. A plurality of ropes connect the first and second side edges of the flexible seating portion to the collapsible spreader bar.

An infant care apparatus including a base, a drive, an infant support, and a controller. The a drive is coupled to the base and has a first electromechanical driver defining a first degree of freedom forming a first axis of motion of a movable infant load seat surface dependent from and movable relative to the base. The infant support is removably coupled to the movable infant load seat surface. The drive is a distributed drive distributed to the base and the infant support, and includes a second electromechanical driver integral with the infant support that defines a second degree of freedom forming a second axis of motion of the infant support. The controller is communicably coupled to the distributed drive and is configured so as to move, via the first and second electromechanical drivers, the infant support relative to the base.

A folding swing chair support, which comprises: two long rod sets formed by cross-hinging two long rods and two short rod sets formed by cross-hinging two short rods. The two long rod sets stand on the front and rear facades, respectively, and the two sides are hinged by short rod sets to form an associated support as a whole; the upper ends of the two long rods in the long rod sets form suspension points, and the lower ends thereof function to support on the ground. The utility model is characterized by ingenious conception, stable structure, folding and unfolding linkage, and smooth operation.

A chair includes a lower chair and an upper chair. The lower chair includes a tilt-swivel mechanism defining a vertical swivel axis, a yoke, and a column extending between the tilt-swivel mechanism and the yoke. The upper chair is pivotably mounted to the yoke about a horizontal upper chair pivot axis. The upper chair includes a seat adapted to cradle the ischial tuberosities of a user.
