The present disclosure relates to a detachable chair leg and a chair. The chair includes feet and a central support. The central support includes a support body and a plurality of mount portions, one side of the foot is provided with a mount groove. The mount portion is horizontally embedded in the mount groove, and a fastening assembly is provided between the foot and the central support to prevent the mount portion from removing laterally from the mount groove. The mount portion is provided with first limit portions, the foot is provided with second limit portions, at least one first limit portion is located at the outer side of the second limit portion along a longitudinal direction, the first limit portions and the second limit portions cooperate to form a longitudinal limit structure that prevents the foot from being separated from the mount portion in the longitudinal direction.

The present disclosure provides a gaming chair. The gaming chair includes a movable stand member, a seat member, a backrest member, a plurality of speakers, a Bluetooth transmitter, a power supply, and an inverted triangle wiring. The seat member is disposed over the movable stand member. Further, the backrest member is hingeably coupled to the seat member. Furthermore, the inverted triangle wiring is adapted to electrically couple the plurality of speakers, the Bluetooth transmitter and the power supply to enable an electrical connection therebetween, thereby making the gaming chair to be musical.

A tablet including a plate member, a support rod and a positioning member is revealed. The plate member has a top cover, a bottom cover, and a first slide member. By the movable engagement of a rack with a damper, the top and the bottom covers slide relative to the first slide member. The support rod includes an upper end for supporting the plate member and a lower end assembled on a chair, a bed, a sofa, a table, a tray with wheels or a multi-seater chair. The upper end forms a rotary shaft which is inserted through an insertion hole of the bottom cover to be fixed on the first slide member. The positioning member includes a movable locking pin member. The angle of the plate member can be adjusted by the locking pin member being released from or locked into a positioning hole on the rotary shaft.

A chair having a separately configured seating assembly and backrest that move together upon reclining movement of a user. The seat assembly can be pivoted between a lowered, seating position and a raised, nesting position. The backrest can be pivoted between an upright position and a reclined position. The seat assembly includes a seat that is movable along seat frame sub-assembly that includes a pair of glide tracks upon the reclining movement of the backrest. A bias member of the seat assembly urges the seat into a retracted position and the backrest into an upright position. The seat assembly is pivotally mounted to the support frame of the chair such that the entire seat assembly can be pivoted to a raised, nesting position. The seat assembly can also be pivoted to a lowered, seating position to allow multiple chairs to be stacked.

An article of furniture has retractable and extendable wheels secured beneath each leg. The mechanism for retraction and extension is accomplished by an activation means in mechanical communication with each wheel.

A wobble base provides a curved floor-contacting surface with one or more alignment posts that align the wobble base to the bottom of a seating platform and one or more holes separate from the alignment posts through which one or more fasteners may be placed to attach the wobble base to the seating platform, thereby providing a wobble stool. The wobble base can be configured to convert an existing stool into a wobble stool by replacing one or more floor-contacting members with the wobble base. In a second embodiment, a seating platform, such as a stool, is provided with both traditional floor-contacting members, such as feet or casters, and with a wobble base that allows the traditional floor-contacting members to be removed and replaced with the wobble base, and allows the wobble base to be removed and replaced with the traditional floor-contacting members.

A spring member is disposed so that a biasing direction is in a forward/rearward direction, and includes a front side engagement portion disposed on a front portion of the spring and a rear side engagement portion disposed on a rear portion of the spring, a seat includes a front side spring receiving portion engaged with a front side engagement portion, a backrest or a support structure includes a rear side spring receiving portion engaged with the rear side engagement portion and an adjustment portion configured to adjust a position of the rear side engagement portion in the upward/downward direction together with the rear side spring receiving portion, and an upper limit position of the rear side engagement portion of the spring member adjusted by the adjustment portion is located above an pivot axis at which the backrest is rotatably supported by the support structure.

A quick-release device is for securing a rod of any gas cylinder into the plate of any chair, item of furniture, or other device supported by a gas cylinder and activating the rod with a button thereon. This universal quick-release device includes a sleeve in in the seat plate, an adapter fit into the sleeve, the adapter including an upper portion and a lower portion with different inner and outer diameters. The sleeve is configured to receive the lower portion of the adapter in a press-fit engagement. The upper portion is configured to receive the rod of the gas cylinder in a removable engagement.

Joystick chair is an input device for interaction between the user and computer. It enables the movement of the user in games. The invention is used by placing feet on the platform (3) and sitting or leaning on the seat (23). Command for turning is achieved by rotating the seat (23), either to the left or to the right. Command for forward movement is issued by pulling the left or right controller (36, 41) with fingers, while the command for backward movement is issued by pushing the left or right controller (36, 41) away by palms. Control handles for lateral movement (49, 56) are separated from the forward-back controls that are located on the controllers (36, 41). Other commands are achieved with buttons on the left and right controller and they are accessible with thumbs. The software allows the modifications of all available actions of the invention.

A removable cushion for a chair having an outer surface and an inner foam, as well as at least one magnetic member. The inner foam and the outer surface are formed from the same polymer, with the outer surface forming an integral skin over the inner foam. The outer surface defines an upper surface and a lower surface. The lower surface is structurally configured to be positioned in an abutting relationship with a seating surface of a chair. The at least one magnetic member is embedded within one of the outer surface and the inner foam, the at least one magnetic member positioned closer to the lower surface than the upper surface of the outer surface. A chair having the cushion, and a mold is likewise disclosed, as is a method of manufacturing the cushion.
