An elastic seesaw-type tilting mechanism is provided, including: a base support, configured to be connected with a chair base through a chair column; a seat support, being pivotably mounted on the base support and configured to be connected with a seat; a backrest support, being pivotably mounted on the base support and configured to be connected with a backrest; a first elastic mechanism, being connected with the seat support and the backrest support to form an elastic seesaw mechanism; a second elastic mechanism, being connected with the base support and the seat support, the second elastic mechanism and the first elastic mechanism being respectively biased against the seat support in opposite directions. A swivel chair is further provided, including: one of the elastic seesaw-type tilting mechanism as described above, a seat, a backrest, a chair column and a chair base.

An office chair comprises a seat element (3) mounted movably on a fixed support element (1) and a back support element (2). The arrangement simultaneously allows the seat element (3) to move and tilt backwards when the user leans backwards. The seat element (3) carries the chair seating panel (4) in such a way that when the user leans to a side, said chair seating panel (4) tilts to the same side according to the user's movement and independently of the chair's back element (2).

Novel tools and techniques might provide for implementing seat lifting. In various embodiments, a seat lifter might include one or more first pistons, one or more second pistons, and a seat portion. The one or more first pistons, when actuated (e.g., in response to user input), might cause a rear portion of the seat portion to lift relative to a front portion of the seat portion, the rear portion of the seat portion being lifted by a first height above a seat to which the seat lifter is affixed. The one or more second pistons, when actuated, might cause the front portion of the seat portion to lift by a second height above the seat, the second height being less than the first height. In some instances, the first pistons and the second pistons might be actuated serially (in either order), or might be actuated concurrently.

An adjustable chair with adjustable features to relieve the pressure on occupant's spine, tailbone, and pelvic bone when in sitting position. The adjustable chair includes a seat assembly and an adjustable support frame underlying the seat assembly with a plurality of legs and support casters. The seat assembly includes a backrest and a seat articulated together adjacent the lower edge of the backrest and rear edge of the seat. The automatic adjustable chair includes plurality of electrically motorized drive system to automate the various adjustable features. These drive systems are controlled by a single controller unit operable by the occupant from the sitting position.

This is directed to a smart ergonomic chair and mobility system. The system can be used as a working station, a working chair, a mobility device, a personal care device, or a combination thereof. The system is designed to provide ergonomic seating posture for a person who is seated on the chair. The system is also designed to reduce body stress by providing automatic movements of parts of the chair at predefined time points.

A recliner system, including a suspension point adapted to be mounted onto an upright anchor and to extend outwardly therefrom. The recliner system further includes a support platform and a plurality of cords, each attached to the support platform at two attachment points and suspended from the suspension point. The support platform is adjustable between an upright position and a reclined position by pulling on at least a subset of the plurality of cords.

A beach cart is formed from a frame that has a pair of wheel trucks depend downwardly from either end thereof. A handle is attached at one end of the frame, either to the frame or to the wheel truck thereat, to pull the cart. A pair of chairs is attached to the frame and each has a base, a back, and a leg rest with the back capable of reclining and the leg rest capable of rotating with respect to the base. A table is located on either end of the frame and each rotates between an upright folded position and a deployed horizontal position. The chair back and leg rest as well as the tables act as sidewall when items are being transported by the cart between two locations.
