What does the Sitness Net Pro 100 do?
This office chair is specifically designed for people who sit a lot and suffer from back problems. The special ring-disc seat with knee roll supports your spine in its natural S-shape and encourages active sitting. Thanks to the tip-synchro mechanism, the backrest moves with your body, which reduces the pressure on your lower back.

Why choose this size and version?
With seat dimensions of 450 x 460 mm and a load capacity of 110 kg, this chair suits most adult users. The height-adjustable seat (460-560 mm) adapts to different body heights. The aluminium base provides stability, while the 650 mm high mesh backrest also offers good support to taller users.

An honest note on back support
The mesh backrest provides good ventilation during long working days, but offers less support than a fully upholstered back. The combination of the ring-disc seat with knee roll and the flexible mesh back works best for people who want to move consciously while sitting. For those who lean a lot or are looking for firm support, this may be less suitable.

Practical compatibility with your workspace
The chair is supplied as standard with carpet castors, ideal for use on floor coverings. Working on a hard floor? You can optionally order hard floor castors (article number 70699952). The armrests are fixed, so check that they fit under your desk. The Trevira CS upholstery is flame-retardant treated, which is particularly important in office environments.
