Gust Heavy Duty Ergonomic Mesh Chair – 160kg

The Gust Heavy Duty Ergonomic Mesh Chair is a commercial task chair with a verified 160kg rating, a super-heavy-duty four-lever ergonomic mechanism, seat-slide adjustment and height-adjustable lumbar support. It is supplied without arms, with compatible Breeze arms available separately for buyers who need arm support. The black mesh back, black fabric seat and black nylon five-star base keep the specification straightforward for workplace procurement. Heavy Duty Ergonomic Chair for Commercial Workplaces This model is built for workplaces that need a stronger ergonomic mesh chair with a wider 540mm seat and a commercial adjustment package. The 160kg rating, BIFMA X5.11 certification and 10-year warranty make it a practical option for offices, control rooms, education facilities, government departments, administration teams and shared work areas where chairs need to suit multiple users. Four-Lever Adjustment and Seat Slide The four-lever ergonomic mechanism gives the user separate controls for key chair settings instead of relying on one basic tilt action. Seat-slide adjustment changes the usable seat depth from 500mm to 560mm, which helps the user position the seat pan more appropriately for leg length and desk-based work. Adjustable Backrest and Lumbar Support The ratchet-height backrest adjustment helps position the backrest height to suit the user. Height-adjustable lumbar support lets the lower-back contact point be moved, while the breathable black mesh back assists airflow during prolonged desk-based work.

Its adjustment range is useful where several staff may use the same chair, while the wider seat and heavy-duty mechanism make it a stronger procurement choice than a standard light-duty mesh task chair. BIFMA X5.11 certification is relevant for commercial buyers because it indicates the model has been assessed against a recognised seating standard. The certification should be read alongside the manufacturer’s 160kg rating, verified dimensions and warranty when comparing options.
