An armrest structure includes a main base tube, an outer base tube, a control member, and a spring, and the control member includes a pivot part, a press control part, a fastening part, and a restraining part, when the press control part of the control member is pressed, the spring is pushed to store elastic energy, and the fastening part of the control member can be released from being engaged with the main base tube, and the outer base tube can be adjusted to longitudinally lift; in the other hand, when the force applied on the press control part of the control member to press and buckle is removed, the fastening pan can be engaged with the main base tube, so that the outer base tube is unable to lift and move relative to the main base tube.

An apparatus that supports a person in a variety of positions so that a tattoo artist can comfortably apply a tattoo to the skin of the supported person is herein disclosed. The apparatus can be articulated to cause a person's legs and arms to be optimally positioned and supported to receive a tattoo.

This disclosure relates to a seat device (1) comprising an underframe (2) and a seat (3) connected to the underframe (2) in such a way as to pivot about a pivot seat axis (A1), there being provided means for elastically biasing the seat (3) in anti-clockwise rotation. The seat device (1) further comprises a lumbar part (42); rotationally secured to the seat (3), and a saddle (5) for supporting the top of the thighs of the user, the saddle (5) being connected to the front region of the seat (3).

A cam adjustment device for lifting and lowering an armrest includes an armrest assembly and a support frame. The armrest assembly includes a connection base. The support frame has a support rod. The connection base is slidably connected to the support rod. A locking mechanism includes a cam wrench disposed on the connection base and rotatably installed on the connection base. The cam wrench is rotated such that a cam on the cam wrench presses and acts on the support rod. In a locked state, the cam wrench presses the support rod such that the connection base and the support rod are kept to be relatively fixed. In an unlocked state, the cam wrench is rotated to allow the cam to be released from the support rod, such that the connection base is lifted, lowered, and adjusted relative to the support rod.

A support component (1) for a chair (3) comprises a rigid base element (11), a support structure (12) and a flexible cover (13). The support structure (12) is mounted on the base element (11) such that there is a space (121) between the base element (11) and the support structure (12) when the support structure (12) is without load. The cover (13) is mounted directly on the support structure (12) so that the cover (13) rests on the support structure (12).

An easily assembled chair armrest is revealed. The easily assembled chair armrest includes an armrest support, an armrest pad body, and at least one fastening member arranged between the armrest support and the armrest pad body. The fastening member includes at least one first fastening portion and at least one second fastening portion which are aligned and pressed vertically to fit and connect with each other. One of the first fastening portion and the second fastening portion is disposed on a top support surface of the armrest support while the other is arranged at a first mounting space of the armrest pad body. While being assembled to form the chair armrest, the armrest support is connected with the armrest pad body to form one part by vertical fastening of the first fastening portion and the second fastening portion of the fastening member. Thus manufacturing cost is reduced relatively.

A reconfigurable chair includes features that open up new sitting and resting positions for the user. The chair includes rotatable lateral side rests and a tilt adjustable back rest which when reconfigured, provide auxiliary resting platforms to support the body in different sitting and resting positions. The backrest may include a rotatable feature so that the backrest may be moved from an upright position to a flat position adding another level of support. A height adjustment mechanism may adjust the height of the backrest to add to the reconfigurability of the chair.
