An armrest assembly includes an armrest body that defines an interior space. A first shaft extends from a first side of the armrest body along an armrest axis and is attached to the armrest body for relative rotational movement about the armrest axis. A second shaft extends from a second side of the armrest body along the armrest axis and is attached to the armrest body for relative rotational movement about the armrest axis. A rotational damper is located in the interior space of the armrest body and includes a first damper part and a second damper part attached to the first damper part for relative rotational movement. The first damper part is fixed to the first shaft, and the second damper part is fixed to the armrest body.

A child accommodating apparatus is provided and includes a frame and an armrest tube. The armrest tube is rotatably connected with the frame. The armrest rotating mechanism is for rotating the armrest tube. The armrest rotating mechanism includes an engagement device and an operation device. The engagement device is disposed between the armrest tube and the frame and for positioning the armrest tube relative to the frame. The operation device is disposed on the armrest tube and connected with the engagement device. The operation device includes a housing coaxially and rotatably sleeved on the armrest tube and rotatable relative to the armrest tube. When the housing of the operation device is operated to rotate relative to the armrest tube, a rotating movement of the housing of the operation device drives the engagement device to disengage the armrest tube from the frame.

The seating assembly provides a seat with adaptable configurations to meet varying venue requirements and safety mechanisms to protect users during setup and use, among other features. The transportation assembly offers compact and intuitive storage solutions for seating assemblies, enhancing operational efficiency and reducing setup and breakdown times of seating assemblies. In sum, this innovative seating system significantly improves comfort, functionality, and durability, which effectively addresses the complex needs of modern venue environments and advances the seating industry.

A functional office chair is provided, which allows users to perform exercise movements without going to the gym, and in which the range of motion of the exercise performed while exercising can be freely adjusted. The functional office chair includes a lower body, an upper body, telescopic rear force arms and front force arms, a connection section, a side bar, a T-bar, and armrests.

A foldable chair is disclosed. The foldable chair includes: a foldable chair frame switchable between a folded state and an unfolded state; an armrest telescopically mounted to the chair frame and movable relative to the chair frame between a retracted position and an extended position; and a locking mechanism mounted to the chair frame and configured to lock the armrest; wherein the locking mechanism is configured to lock the armrest in the extended position when the chair frame is in the unfolded state, and to unlock the armrest in response to the chair frame switched to the folded state to allow the armrest to be moved from the extended position toward the retracted position. The configuration of the foldable chair allows the armrest to be unlocked by folding the chair frame and be easily moved to the retracted position by, for example, pushing the armrest, thereby realizing convenient folding of the foldable chair. Moreover, the armrest does not need to be rotated when the armrest is retracted during the folding process of the foldable chair, avoiding the hands from getting pinched by the armrest.

A portable storage and seating device, or apparatus, is disclosed. The device comprises a folding leg rest, a folding back rest, arm rests, a sliding head rest, a pair of wheels, a handle, a rear compartment, and at least one side compartment. The portable storage and seating device is configured to be compact when folded and easily maneuverable. The portable storage and seating device is able to store various items for outdoor activities and provides attachment points for accessories.

An armrest frame capable of being collapsed conveniently is provided. The armrest frame capable of being collapsed conveniently includes an armrest frame set, scissor sets, and a locking unit, where the scissor sets are provided between the armrest frames, the scissor sets drive the armrest frames to move close to or away from each other, the scissor sets each include crisscross hinged scissor arms, and two ends of each of the scissor arms are respectively hinged to the corresponding armrest frames. The armrest frame set is used to replace the existing fixed wood frame or metal frame. In the armrest frame set, one armrest frame is fixed, while the other armrest frame is movable. The movable armrest frame can move relative to the fixed armrest frame through the scissor set, such that an armrest of a sofa can be expanded or collapsed.

An adjustable multi-use chair is provided with two adjustable chair backs and armrests, and the height of a first chair back is adjustable; an angle between a second chair back and a seat surface of a seat is adjustable, such that the second chair back can function as a chair back or a desk; and angles between inner sides of the two armrests and the seat surface of the seat can be separately adjusted to a plurality of angles from an acute angle to a reflex angle, and users can adjust the armrests according to their preferences to sit forward, lie on the side, sit laterally or backward on the chair and can change their sitting position without being limited by the armrests; and the whole chair is easy to adjust and can be adjusted in multiple ways to satisfy different adjustment requirements of users.
