This office chair supports your back all day thanks to the special spinal seat with knee tilt and breathable mesh backrest. The point synchro mechanism moves smoothly with you, while the armrests offer extra comfort during long work sessions.
When do you choose this product?
What does an ergonomic office chair with special back support do?
This Topstar Sitness Net Pro 100 is designed for people who sit for long periods and want optimal support for their spine. The chair features a special bandenScheibensitz with knee roll, which means your lower back and knees are kept in a natural position during long working days.
Why choose this load capacity and dimensions?
With a load capacity of 110 kg, this chair suits a wide range of users. The seat measures 450 x 460 mm and is infinitely height-adjustable from 460 to 560 mm, so you can always find the right sitting position. The 650 mm high backrest provides sufficient support for the entire back.
How do the mesh back and synchro mechanism work?
The backrest has a mesh cover that ensures good ventilation during work. The point synchro mechanism ensures that the seat and backrest move in sync when you lean back, supporting the natural movement of your body. The aluminium five-star base gives the chair a sturdy foundation.
Practical tip for different floor types
The chair comes as standard with carpet castors, ideal for use on floor coverings. Are you working on a hard floor such as parquet or tiles? Then you can optionally order hard floor castors (article number 70699952). These castors protect your floor from scratches and roll more smoothly over hard surfaces.
