A collapsible chair may be supported by a base. A slider receptacle may be mounted on the base and comprise two arched slider receiving areas. Each arched slider receiving area may be shaped as an arched guide, track or hollow cylinder suitable for receiving two arched sliders, where each arched slider may be inserted and adjustably moved by hand in one of the two arched slider receiving areas. Moving the arched sliders towards a front of the collapsible chair reclines the collapsible chair while moving the arched sliders towards a rear of the collapsible chair raises the collapsible chair. The collapsible chair may also have two back rest poles and two seat poles that create the frame of the collapsible chair. A material may be extended between distal ends of the two back rest poles and two seat poles to create a seating area of the collapsible chair.

A chair having a seat portion that is capable of selectively moving between a rocking position and a stop position, the seat portion being joined to a bottom support comprising a rocking section, a flat section, and a transitional section, the rocking section having a defined curvature and extending between a front end of the bottom support component and the transitional section, the flat section having a substantially flat portion extending between a back end of the bottom support component and the transitional section, in the rocking position the chair is movable along the defined curvature of the rocking section, in the stop position the chair is configured to limit movement of the chair to the stop position, wherein the chair transitions between the rocking position and stop position by rotating past the transitional section of the bottom support.

A rocking furniture member may include a base frame, a seat assembly, a legrest mechanism, and a pawl assembly. The seat assembly may include a ratchet rack having a plurality of teeth. The pawl assembly may include a support link, a pawl arm, and an actuation link. The support link is rotatably coupled to the base frame. The pawl arm is rotatably attached to the support link and selectively engages one of the ratchet teeth. The actuation link may be attached to the pawl arm and may be coupled to the legrest mechanism such that movement of the legrest mechanism into the extended position moves the pawl arm into engagement with the ratchet rack and movement of the legrest mechanism toward the retracted position causes rotation of the pawl arm relative to the support link and disengages the pawl arm from the ratchet rack.

The invention relates generally to a system and methods for facilitating correcting and maintaining a good posture. More specifically, the invention is directed to a posture correcting chair including a seating component, a pump mechanism, and a frame assembly. The seating component may include an inflatable element and a base element. The inflatable element and the base element form a housing. The pump mechanism may include a pumpsuch as a mechanical or electrical pumpfor pumping a medium into or out from the housing such that an occupant of the seating component may maintain a good posture.

A chair support shell has an integral back portion, seat portion, and joining portion between the back portion and the seat portion. At least a major portion of the support shell comprises a compliant structure, the compliant structure having a plurality of cells interconnected by a plurality of resilient members. The compliant structure provides compliance in the seat portion, compliance in the back portion, and compliance in the joining portion. The compliant structure enables recline of the back portion relative to the seat portion.

A chair that provides movement of a seat about an axis of rotation above the seat plane with the seat having a sensor in communication with a computer system that tracks movement. The seat may be simultaneously pivotable about a second axis of rotation defining a range of motion for the seat about the two axes. An actuation system in communication with the computer system can move the seat to desired positions and/or prevent the seat from being positioned at certain locations within the range of motion. The computer system may also include an application that can promote user movement within the seat and allow movement of the seat to be used for gaming, health monitoring and treatment, activity tracking, and the like. The chair may include a mechanism that has one or more glides operably received in curved structures to provide the movement about the axes.

A chair includes: a leg 1; a seat 2; and a front-back support mechanism 4. The front-back support mechanism 4 is provided at a seat receiving part 50 directly supported by the leg 1, and the front-back support mechanism includes: a wavy plate 56 provided to horizontally extend from vertical walls 51 of the seat receiving part 50 and having mound-shaped surfaces 57, 58 each convexly curved upward; and followers 53, 54 provided at front-back support bodies 52 as supported parts and configured to move relative to the mound-shaped surfaces 57, 58 while contacting the mound-shaped surfaces 57, 58. The wavy plate 56 is associated with the followers 53, 54 such that a movement end inclines downward when the seat 2 moves from a neutral position in accordance with a relative movement between the mound-shaped surfaces 57, 58 and the followers 53, 54.
