Ergonomic mesh task chair with headrest

The BOSS B6338-HR is a contemporary office chair built around a breathable mesh back that prevents heat and moisture build-up during long sessions. A ratchet back with active lumbar support adapts to the user's spine for sustained comfort. Height and width adjustable arms let each person set their preferred position. The integrated headrest adds neck support for extended desk work.

Three-paddle multi-function tilt and pneumatic lift

A three-paddle mechanism allows the seat and back to be independently adjusted and locked at any angle within the tilt range. Seat tilt lock secures the seat throughout its travel while adjustable tilt tension controls recline resistance. Pneumatic gas lift provides smooth seat height adjustment for different desk heights. The 27 nylon base with hooded double-wheel casters delivers stable mobility on office flooring.

Adjustability features that change daily use

Independent seat and back locking lets the user switch between upright typing and reclined reading without readjusting lumbar depth. Adjustable tilt tension matches recline feel to body weight so the chair does not push back too hard or too softly. Height and width adjustable arms clear desk edges and support forearms at the correct height. The included headrest completes the ergonomic package for users who need neck support.

Questions about this item

How do I install the 27" nylon base and hooded double wheel casters on the B6338-HR chair?

Insert the five casters firmly into the base holes until they click, then lower the gas lift cylinder into the centre hole of the base before placing the seat assembly onto the cylinder. The step often missed is not seating the casters fully, which causes wobble.

What maintenance or replacement will the pneumatic gas lift on the B6338-HR need over time?

The gas lift may lose pressure after extended use, causing the seat to sink. If this occurs, the cylinder can be removed from the base and replaced with a standard office-chair pneumatic lift of the same stroke length.

What is the first limit that appears during sustained use of the mesh back and multi-function tilt on the B6338-HR?

Under continuous daily use, the adjustable tilt tension spring can fatigue first, reducing the range of resistance settings and making it harder to lock the seat and back at preferred angles.
