When do you choose this product?
When should you choose an office chair with a mesh back?
An office chair with a mesh back is ideal if you sit at your desk for long periods every day and value good ventilation. The breathable mesh upholstery prevents your back from getting sweaty and keeps a pleasant temperature, even during intensive working days. This type of chair is perfect for modern office environments where comfort and functionality go hand in hand.
Why choose these compact dimensions?
With seat dimensions of 480 x 480 mm, this chair offers a compact seat that suits most users without taking up too much space. The height adjustment from 420 to 570 mm makes it possible to adapt the chair to different body heights. These dimensions make the chair especially suitable for standard office workstations and home offices with limited space.
Adjustability for optimal support
What sets this chair apart is the combination of height- and tilt-adjustable back support of 580 mm high. This allows you to adjust the backrest to your natural working posture and helps prevent back complaints. The stepless seat height adjustment ensures you can always adopt the right working posture, regardless of your height.
Practical considerations for daily use
The chair has a load capacity of 110 kg, making it suitable for most users. You can add armrests later (type P4 with code 77400128) if you want more arm support. The black polyamide base is sturdy and complements the light grey seat and black mesh back, so the chair fits in almost any office interior.
