An armrest according to the present invention includes a support member (8a, 215, 308a) which is a support structure, and an armrest main body (8b, 216, 308b), the armrest main body (8b, 216, 308b) includes a lower layer member (8j) including an operation lever (8p, 235, 308p) which is supported by a support member (8a, 215, 308a) to be movable in a forward-and-rearward direction and is operated by a seated person, and an upper layer member (8k) supported by the lower layer member (8j) to be movable in right-and-left direction, and the upper layer member (8k) covers the operation lever (8p, 235, 308p) at a base position in the right-and-left direction.

A height-adjustable armrest for a chair, in particular an office chair, has an arm support, which is retained by an armrest holder. The armrest holder is pivotable and a pivoting causes the armrest to be adjusted in height. An arresting device fixes the armrest holder in a height position. The arresting device is arranged at the upper, alterable-height end of the armrest holder and has a linearly movable latching element. The latching element is connected via a guide element to the armrest holder such that each pivoting movement of the armrest holder induces a linear movement of the latching element.

An arm assembly for a chair having a post, a first member, and an armrest. The first member is angularly adjustable relative to the post about a first axis between first angular movement limits, with a non-finite number of angular adjustment positions of the first member relative to the post. The armrest is operatively connected to the first member to translationally slide generally forward and rearward relative to the first member between first translational movement limits, with a non-finite number of translational adjustment positions of the armrest relative to the first member. The armrest is angularly adjustable relative to the first member about a second substantially upright axis between second angular movement limits, with a non-finite number of angular adjustment positions of the armrest relative to the first member.

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 intelligent massage chair is provided. The chair includes a chair frame and armrests connected on left and right sides of the chair frame. At least one of the armrests is connected to the chair frame through a flipping device. The flipping device includes a base connected to the chair frame and a flipping fixed seat rotatably connected to the base around a rotation axis extending left and right, the flipping fixed seat is fixed to the at least one of the armrests. When the flipping device flips the armrest to a set position, the chair frame has a side entrance on the side of the armrest. The armrest can be rotated open from the side to form a side entrance for users to sit in the massage chair from the left and right sides, which is convenient for users to sit in the massage chair.

A lounge chair includes a frame including an upper body section, and a lower body section, a support section and support material. The upper body section is operatively coupled to the lower body section to pivot between a plurality of angular positions. The upper body section includes an aperture extending through the support material to receive the face of an individual when lying in a supine position. The lower body section is operatively coupled to the support section with an anterior tilt. The lounge chair includes armrests which pivot incrementally between a plurality of angular positions in a direction transverse, parallel or both transverse and parallel to a plane of a side member of the lower body section.

A chair component assembly includes a support component adapted to support a portion of a seated user, and a cover including a plurality of sides that cooperate to form an interior space that receives the support component therein, the cover further including a support component receiving aperture and a flap movable between an open position where the support component may be moved from an exterior of the cover to the interior space of the cover, and a closed position where the flap covers the support component receiving aperture, and wherein the flap is secured to the support component by a quick-connect fastener.

A chair assembly includes a four-bar arrangement that includes a lower end and an upper end where the upper end is adjustable between a raised position and a lowered position, and an arm rest assembly adapted to support the arm of a seated user thereon and supported on an upper end of the four-bar arrangement, wherein the lower end of the four-bar arrangement is pivotably supported from an arm support structure for pivotable movement about an arm pivot axis, such that the upper end of the four-bar arrangement is movable between a first position and second position located laterally outward from the first position, and wherein the arm pivot axis is angularly offset from a vertical axis.

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.

A sitting apparatus having: a frame; an upwardly facing surface on the frame for supporting a user in a sitting position; a first arm support on the frame defining a first surface against which a user's arm can be rested with the user in the sitting position on the upwardly facing surface; and a first connecting assembly acing between the frame and first arm support. The first connecting assembly and first arm support are configured so that the first arm support surface can pivot relative to the frame around at least first and second different axes to change a relationship between the first arm support surface and the frame.
