The present invention relates to a chair equipped with supporter for shoulder which can obtain an effect of attitude remedy by reducing the pressure applied to the spine and by inducing an upright attitude of erecting the waist vertically through the supporter for shoulder which is connected to the hip supporter through the base and which comprises the supporter for armpit provided above the supporter, and in addition which can maximize convenience and enable the multi-purpose use by selecting the use and non-use of the supporter for arm or the supporter for shoulder through the direction change through up-down or forward-rearward direction rotation of the supporter for arm or through the folding of the supporter for armpit of the supporter for shoulder through the rotation shaft.

The chair equipped with supporter for shoulder according to the present invention comprises: a base; a hip supporter provided above the base; a supporter for shoulder comprising a supporter connected to the base and protruding to both sides of the hip supporter, and a supporter for armpit provided above the supporter; and a supporter for arm connected to the base and provided below the supporter for armpit.

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.

Seating assemblies and methods are disclosed. A seating assembly can comprise a seat, a back support, and a frame component. The frame component can extend from a bottom portion, positioned near an underside of the seat, to a top portion, configured to maintain the back support at a position above the seat. The back support can laterally extend from a left edge portion to a right edge portion and can include a spring member at or near each of the left and right edge portions. The spring member can include at least one undulation or are providing integrated compression adaptation to a user. The seating assembly can further comprise a tilt mechanism, engaged with the frame component, including one or more leaf springs and a spring contact assembly. The spring contact assembly can be positioned on a top side of the one or more leaf springs.

A sofa armrest folding mechanism and a sofa armrest are provided. The sofa armrest folding mechanism includes: side boards, a handle, and folding devices, where the side boards are connected to two sides of the folding devices, respectively; two ends of the handle are connected to top ends of the folding devices, respectively; the folding devices switch between a folded state and an unfolded state through the handle; when the handle is pulled upwards, the folding devices are in the folded state; and when the handle is pushed downwards, the folding devices are in the unfolded state. Connecting teeth on each two adjacent connecting rods are engaged, and the handle is pulled upwards or pushed downwards to drive the side boards to move close to or away from each other, achieving a change in the overall structural state.

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. A method for using a stool can involve rotating armrests of the apparatus from a stowed position to a deployed position. The armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool.

A chair for providing seating support to a user and for providing ways for the user to perform exercises. The chair includes a back support that is flexible such that when a force is applied to it by the user's body, the back support bends. The back support may be configured to adapt to the curvature of the user's spine when the user is seated in the chair. The back support may further be configured such that the user can rotate the back support by rotating the user's upper body.

An armrest expansion device. The armrest expansion device can include two or more planar housings and couplings for reversibly coupling the device to a pre-existing armrest, for example a commercial passenger vehicle's armrest, or any other desired armrest. At least one of the planar housings may extend the useable area available as an armrest. Further, the armrest expansion device may additionally increase the effective height of the pre-existing armrest.

An apparatus that supports a user in a variety of positions to comfortably perform tasks, such as applying one or more tattoos to skin of a subject is herein disclosed. The apparatus can be reconfigured to optimally position and support the arms and/or chest of the user. The apparatus includes a vertically movable armrest assembly. Armrests can support the user's forearms while supporting the user's chest such that the user can comfortably perform tasks in front of a chest support of the stool. The armrest assembly can be translated vertically to accommodate the user's body to achieve desired positioning.

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.

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.
