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.

An exercise chair allows a user to obtain physical exercise at his or her desk or other workplace. An exemplary exercise chair may include a frame, including a base, an angled section angled upward from the front of the base, and a back support extending upward from the rear of the base; a seat support rotatably connected to the angled section; and at least one resistance element connected to a rear portion of the seat support and to the back support.

A seating arrangement includes a rigid back frame, a flexible back shell coupled to the back frame and including a pair of vertical side portions and at least two strap portions extending laterally between the side portions and including a forwardly-facing surface configured to support a back of a seated user, the at least two strap portions including a lowermost strap portion, the lowermost strap portion configured to deflect a first distance when a rearwardly-directed force is exerted on the lowermost strap portion by a seated user, and a lumbar assembly supported from the back frame and configured to support the lumbar region of a back of a seated user, the lumbar assembly configured to deflect a second distance when the rearwardly-directed force is exerted on the lumbar assembly by a seated user, wherein the first distance and the second distance are substantially similar.

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 dynamic furniture system includes a first frame portion; a set of rollers mounted to the first frame portion; a second frame portion including one or more rockers having a roller-interface surface having a curved profile; wherein the set of rollers interface with the roller-interface surface of the rockers such that the second frame portion is moveable relative to the first frame portion; a set of one or more electromagnets mounted to or integrated with the first frame portion or the second frame portion; a set of one or more magnetically-interactive elements mounted to or integrated with a different one of the first frame portion or the second frame portion; and an electronic control system configured to vary a parameter of electrical energy supplied to the set of electromagnets over time to induce back and forth motion of one of the first frame portion or the second frame portion.
