A seating arrangement includes a rigid back frame, a flexible back shell coupled to the back frame and including a pair of vertical side portions and at least two strap portions extending laterally between the side portions and including a forwardly-facing surface configured to support a back of a seated user, the at least two strap portions including a lowermost strap portion, the lowermost strap portion configured to deflect a first distance when a rearwardly-directed force is exerted on the lowermost strap portion by a seated user, and a lumbar assembly supported from the back frame and configured to support the lumbar region of a back of a seated user, the lumbar assembly configured to deflect a second distance when the rearwardly-directed force is exerted on the lumbar assembly by a seated user, wherein the first distance and the second distance are substantially similar.

In an aspect, provided is an adjustable telescoping assembly. The adjustable telescoping assembly comprises a first support member and a second support member that is slidable upon the first support member and which defines an interior volume. At least one damping element is provided that extends from outside the second support member, through a corresponding damping element aperture on the second support member into the interior volume and engages the first support member.

A seating arrangement includes a back frame that includes a top portion, a bottom portion, and a pair of side portions that cooperate to define an opening, wherein at least one of the top portion, the bottom portion and the side portions include a longitudinally extending channel, a back shell having a forwardly facing support surface located within the opening and configured to support a seated user, and an attachment portion that extends about at least a portion of a periphery the support surface, and a cover member extending over the support surface, wherein the cover member is directly attached to the attachment portion of the back shell at an attachment location, and wherein the attachment location and the attachment portion of the back shell are located within the channel and concealed from view.

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 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.

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 multi-directional adjustable armrest pad and a chair armrest device with an armrest pad are disclosed and three embodiments are provided. In an embodiment, the pad body can be adjusted to move in a longitudinal direction and a lateral direction, and rotate relative to the chair armrest, and the pad body can be lifted by controlling a regulating assembly, and the regulating assembly is also rotatable and pivotally swingable, so as to make the armrest pad suit placement of a user's hand when the user sits on the chair.

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 seating arrangement includes a seat assembly slidably movable between a forward most position and a rearward most position and that includes a seat support structure configured to support a seated user thereon, and at least one elongated slide bearing attached to the seat support structure and including a bearing surface and at least one stop member, wherein the bearing surface and the at least one stop member are a single, integral piece. The seating arrangement further includes at least one slide support member that slidably supports the slide bearing thereon between the forward most position and the rearward most position, wherein the at least one stop member is configured to prevent the seat assembly from being moved beyond at least one of the forward most position and the rearward most position.

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.
