An ottoman linkage is provided that moves a footrest from a closed position to an extended position. The ottoman linkage includes a front ottoman link coupled to a seat mounting plate, and an outside ottoman link pivotally coupled to the front ottoman link. A rear ottoman link is coupled to the seat mounting plate and the outside ottoman link. An inside ottoman link is pivotally coupled on a first end to the front ottoman link, and pivotally coupled on a second end to a footrest bracket, the inside ottoman link being generally in-line with the outside ottoman link when the mechanism is in an extended position, and the outside ottoman link having a width that obscures the inside ottoman link from view.

A furniture member may include a base frame and a seat assembly mounted on the base frame. The seat assembly may include a seat frame, a seatback, a seat bottom, a rocker member, a legrest mechanism, and a tilt mechanism. The rocker member is attached to the seat frame and rollingly contacts the base frame. The rocker member supports the seat assembly relative to the base frame such that the seat assembly is movable between a rocked-back tilt position and a rocked-forward tilt position. The legrest mechanism is mounted to the seat frame and attached to a legrest platform. The legrest mechanism may include a drive rod coupled to a pantograph linkage that is movable relative to the seat frame between retracted and extended positions. The tilt mechanism selectively locks the seat assembly in one of an infinite number of tilt positions between the rocked-back and rocked-forward tilt positions.

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.

The present disclosure relates to a mechanical extension apparatus for an extendable chair unit and a chair unit including such mechanical extension apparatus. The mechanical extension apparatus includes: a reclining apparatus that include multiple links attached to the seat, the backrest and the footrest of the extendable seat, and such reclining apparatus is configured to convert the extendable seat between a sitting position and a lying position. The mechanical extension apparatus also includes an actuator that is attached to the reclining apparatus, and the actuator is configured to electronically convert the extendable seat between the sitting position and the lying position.

Dynamic furniture for supporting a user includes an actuator assembly, a seat platform, and a back platform. The actuator assembly includes an arcuate member in single path eccentric orbital contact with the ground. The seat platform is in single path orbital connection to the actuator assembly. The back platform is in single path orbital connection to the actuator assembly. The actuator assembly supports the seat platform and the back platform.

A virtual-reality navigation controller includes a base, a seat, a vertical support to support the seat on the base, and a rotatable connector between the seat and the vertical support to tilt the seat about a rotational center of the rotatable connector in response to directional forces exerted by a user seated on the seat. The virtual-reality navigation controller further includes a motion-detection controller to measure pitch corresponding to the tilt of the seat resulting from the directional forces.

A virtual-reality navigation controller includes a base and a seating portion. The seating portion includes a seat for supporting a weight of a user seated thereon and a back-rest coupled to the seat to move integrally with the seat and to support the user's back. The virtual-reality navigation controller further includes a vertical support to support the seating portion on the base, and a rotatable connector between the seating portion and the vertical support to tilt the seating portion about a rotational center of the rotatable connector when the user is seated on the seat. A radius of an arc formed by the tilting about the rotational center ranges from 300 mm to 800 mm. The virtual-reality navigation controller further includes a motion-detection controller to measure pitch corresponding to the tilt of the seating portion.

A furniture member rocker spring assembly includes first and second bracket members arranged in mirror image configuration. First and second springs are positioned between and in direct contact with each of the first and second bracket members. A restrictor bolt assembly is positioned intermediately between the first and second springs. The restrictor bolt assembly includes at least one sleeve member received in an aperture of the first and second bracket members and a fastener that extends through a sleeve bore in the sleeve member. The sleeve member is arranged in sliding contact with at least one of the first and second bracket members.
