The invention relates generally to a lightweight, collapsible, and portable wheeled seat, e.g., a wheeled office chair or stool, for travel, storage, and mobility. The seat includes a seat base member and a seat surface member collapsible between an open, extended position, which is configured to provide a seating surface, and a collapsed, closed position. The seat surface member includes a central seating surface member fixed to the seat base member that has an outer perimeter, and a pair of oppositely disposed and generally u-shaped seating surface members pivotally secured to the seat base member. Each of the generally u-shaped seating surface members include a pair of leg portions that extend from a base portion thereof, or an inward directed perimeter and a portion of each inward directed perimeter has a shape that substantially complementarily corresponds to a shape of a portion of the outer perimeter of the central seating surface member.

An adjustable rotary rocking chair having a chair frame assembly A, an adjustment mechanism B, and a support tube assembly C, wherein the adjustment mechanism B is detachably connected with the chair frame assembly A and is connected with the support tube assembly C in an insertion manner. The adjustable rotary rocking chair can swing and rotate, has higher flexibility and adaptability due to the fact that the height of the rocking chair and the height of the support tubes can be automatically adjusted by users, is portable through a folding design, and can be used indoors and outdoors.

A canopy assembly for a chair, the assembly including a first mounting fixture and a second mounting fixture; a first arm and a second arm, each arm having a first end and a second end, wherein the first end of each arm is coupled to a respective mounting fixture; a first canopy support and a second canopy support, wherein the second end of each arm is coupled to a respective canopy support; a first brace and a second brace, each brace coupled between a respective arm and canopy support, with a first end of each brace being coupled to the respective arm with a slidable coupler so as to permit the rotation of the first and second canopy supports relative to the first and second arms; a cross-member coupled intermediate the first and second canopy supports, for maintaining the first and second canopy support at a predetermined spaced distance from each other; and a canopy that is at least supported by the first canopy support and the second canopy support; wherein when the canopy assembly is in a deployed position, the cross-member maintains the first and second canopy supports at the predetermined spaced distance from each other; and when the canopy assembly is in its stowed position, the cross-member maintains the first and second canopy supports at the predetermined spaced distance from each other. A combination canopy assembly and a chair is also disclosed.

An armchair includes a base, a backrest pivotally connected to the base by a first rotating shaft, an armrest connected to the base and an elastic assembly fixed on the armrest. The backrest and the elastic assembly are pivotally connected by a second rotating shaft. The elastic assembly is configured to provide elastic force when the backrest swings around the first rotating shaft. The elastic assembly arranged between the backrest and the armrest permits the backrest to be able to swing relative to the base. In use, the elastic assembly controls the swing amplitude of the backrest according to the pressure exerted by the user's back on the backrest. When the user reclines backward, the elastic assembly acts as a cushion to support the backrest to slowly swing backward due to the elastic force. When the user rises, the elastic force of the elastic assembly urges the backrest to reset.

A height adjustable chair includes a user support platform assembly, and posterior and anterior leg assemblies. The user support platform assembly includes first, second, and third platform portions, and a pair of pivot mechanisms. The posterior and anterior leg assemblies include laterally opposed upper leg portions, laterally opposed lower leg portions, and locking mechanisms for locking the lower leg portions in extended relation relative to the upper leg portions. The pivot mechanisms pivotally attach to first platform portion and the posterior leg assembly. The anterior leg assembly is pivotally attached to the posterior leg assembly, the first platform portion, and the third platform portions. The first support platform supports a user thereupon. The anterior and posterior leg assemblies enable the user to vary the height of the first support platform relative to a support surface.

A folding chair (100) comprises as main components a mainframe (1), a seat (2) and a back leg support (3). At least one of the main components is uniplanar and the others fit within a plane of the at least one main component when the chair (100) is collapsed. The folding chair (100) uses a type A construction, and forward movement of the top of the seat (2) relative to the mainframe (1) causes the back leg support (3) to move backwards relative to the mainframe (1).
