A clip has an engagement portion including: a first arm with a first claw at the top end side; a second arm with a second claw at the top end side; and a bottom provided at the respective base end sides of the first arm and the second arm. Projections of the first claw and the second claw defines a left-right width of a mouth. A third claw projects into the retaining space at a position closer to the base end of the first arm, and a fourth claw is provided which projects into the retaining space at a position closer to the base end of the second arm. The third claw is narrower than the first claw in their widths along a front-back direction orthogonal to the depth direction of the retaining space extending from the mouth to the bottom and the left-right width direction of the mouth.

A method of constructing a seating arrangement that includes providing a first chair structure comprising a first polymeric material having a first surface and a second surface, the first chair structure including at least one attachment area, providing a second chair structure, locating the second chair structure proximate the first chair structure such that at least a portion of the second chair structure covers the first chair structure, providing at least one staple member comprising a second polymeric material, wherein the second polymeric material of the at least one staple member may be recycled with the first polymeric material of the first chair structure without requiring separation of the at least one staple from the first chair component and inserting the at least one staple member through the first chair structure and the second chair structure, thereby securing the first chair structure to the second chair structure.

A system and method for forming a foundation truss for a box spring or mattress foundation frame includes a first truss rail assembly station having a series of block feeders, a top rail hopper and a filler strip hopper that received stacks of truss components such as blocks, top rails and filler strips and feed such truss components into stacked registration. The stacked truss components are moved into engagement with a series of staplers that secure the filler strips, top rails and blocks together to form first truss rail portions, which are then fed to a second truss rail assembly station where a bottom rail is automatically applied thereto.

Methods and systems for no-glue pocketed spring unit construction. Rows of pocketed springs, preferably arranged into modules of more than two pocketed springs surrounding a central hole, are ultrasonically welded together when paired vibrating probes and anvils press layers of pocketed spring fabric from the rows of pocketed springs together and a welding pulse is transmitted to the vibrating probe.

An armrest assembly includes a unitary armrest subassembly having a support substrate and a resilient web secured together by a mechanical fastening feature. The armrest subassembly also includes a cushion overlying the resilient web and a coverstock concealing the cushion and the resilient web and enclosing the receiver in the unitary armrest subassembly that holds those components.

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.
