Abstract: An armrest for a chair includes a first slideable member moveably positioned within a support post and a second slideable member moveably positioned within the support post. The first slideable member is moveably positioned within a channel of the second slideable member such that the first slideable member is moveable relative to the second slideable member. An actuator is connected to the first and second slideable members. The actuator can optionally be included that is actuatable from a locked position to an unlocked position. The first and second slideable members are immovable within the post when the actuator is in the locked position and the first and second slideable members are moveable within the post when the actuator is in the unlocked position.

Abstract: A chair includes a backrest swivel mechanism that is configured to permit the backrest to swivel about a vertical axis about a preselected range of motion. The backrest may be configured to swivel, or rotate, about a vertical axis that is defined by an element located adjacent a rearward central location that is below the seat of the chair and adjacent a rear of the chair. A lock mechanism can be selectively engaged to lock and unlock the swiveling mechanism so that when in the locked state, the backrest cannot swivel and when in the unlocked state, the backrest can swivel. In some embodiments, the range of swiveling motion may be with a predefined range, such as +/?10° or +/?20° of rotation relative to a central position of the backrest.

Abstract: A method of assembling a chair includes providing a first chair component composed of a first polymeric material and a second chair component composed of a second polymeric material. An adhesive is positioned on or in the first chair component. The adhesive is composed of a third polymeric material and at least one ferromagnetic susceptor. The second chair component is positioned in engagement with the adhesive and adjacent to the first chair component. A magnetic field or electromagnetic waves are applied to the adhesive to activate the adhesive. A force is also applied to at least one of the first chair component and the second chair component to press the first chair component and the second chair component. A chair is also provided that includes the first and second chair components and the adhesive.

Abstract: A method of attaching furniture components includes providing a first furniture component that may be comprised of polymeric material, positioning a second furniture component adjacent to the first furniture component, positioning stakes attached to the second component through holes formed in the first component, and heating the stakes to bond portions of the second component to portions of the first component. The second component may also be comprised of polymeric material and the stakes may be integral with the second component or formed on the second component. Chairs or other furniture such as office furniture may include components attached together by embodiments of the disclosed method. In some embodiments of the method, a second component may also have projections that are positioned through holes in a third furniture component that may subsequently be heated to bond the third component to the second component.

Abstract: A method of laser welding chair components together is provided. The method includes selecting at least one first chair component comprised of a first polymeric material that is at least substantially translucent to a laser and selecting at least one second chair component comprised of a second polymeric material that is opaque to the laser such that the one or more second chair components will absorb at least a portion of the heat or energy provided by the laser. The one or more first chair components are laser welded to the one or more second chair components. A chair is also provided that includes a first component composed of polymeric material laser welded to a second component composed of polymeric material.
