When do you choose this product?
What does the Sitness Net Pro 100 do?
This office chair is specifically designed for people who sit for long periods and want to actively work on their posture and back health. The chair combines a special ball-disc seat with a knee roller and a breathable mesh backrest, so you sit actively while you work.
Why choose the mesh backrest variant?
The mesh backrest ensures optimal ventilation during long working days and prevents sweatiness. With a height of 650 mm, the backrest provides sufficient support for your entire back. The combination of the breathable mesh back and the special ball-disc seat with knee roller encourages a healthy sitting posture.
How does the point-synchronous mechanism work?
The point-synchronous mechanism ensures that the backrest and seat move in sync with your body. You can adjust the seat height steplessly between 460 and 560 mm, making the chair suitable for different body heights. The load capacity of 110 kg makes this chair suitable for most users.
Practical considerations when using the chair
The chair is supplied as standard with carpet castors, ideal for use on soft floor coverings. For hard floors, you can optionally order castors for hard floors (article number 70699952). The aluminium five-star base and Trevira CS upholstery ensure durability and easy maintenance of your workspace.
