Guest chair with leather upholstery

The BOSS Office Products B689 is a black guest chair built for reception areas and meeting rooms. It features LeatherPlus upholstery, a polyurethane-infused leather designed for softness and durability. The frame assembles without tools for quick setup. Adjustable functions include pneumatic seat height, tilt tension and an upright locking position.

Suits visitors and side-of-desk seating

This model suits offices that need comfortable visitor seating with ergonomic back support and a waterfall seat edge that reduces leg pressure. The upright lock keeps the backrest fixed for formal meetings. Buyers who need a chair for continuous all-day desk work should look at a task chair with full adjustability.

LeatherPlus upholstery and tool-free assembly

The defining specification is the LeatherPlus material, a leather and polyurethane blend created for a softer feel and longer wear than standard bonded leather. Combined with the no-tools-required frame, it determines whether this chair matches the aesthetic and maintenance needs of a shared workspace.

Questions about this item

What existing desk height works with the pneumatic gas lift seat height adjustment on the B689?

The pneumatic gas lift lets you raise or lower the seat to match most standard desk heights without tools.

Can the upright locking position and adjustable tilt tension on the B689 accommodate an older fixed-height workstation?

Yes, the upright lock and tilt tension adjust independently so the chair stays comfortable at a legacy desk height.

How can I confirm the LeatherPlus upholstery on the B689 is performing as intended after assembly?

The seat should feel supple yet resistant to creasing, and the waterfall front should relieve pressure behind the knees when seated.
