This office chair moves smoothly with you thanks to the synchro mechanism and three-dimensional seat. The lordosis support relieves your lower back, while the armrests provide extra support during your working day.
When do you choose this product?
When do you need an office chair with a synchro mechanism?
The Topstar Sitness Airwork G is intended for normal use in a business or home office and suitable for everyday office work. The synchro mechanism ensures that the backrest and seat move together. The mechanism can be locked in multiple positions and the tilt tension is adjustable to your weight.
Why choose this three-dimensional seating concept?
This chair has a special flat seat with integrated 3D movement, allowing the seat surface to move three-dimensionally. In addition, the chair features an integrated sliding seat.
Support where you need it
The backrest is fitted with sandwich upholstery and a height-adjustable lumbar support. The backrest height is 575 mm. The seat height is infinitely adjustable between 450 and 570 mm, so you can set the seat to your own size. The armrests (type O2) are height-adjustable and included, with soft pad rests, and adjustable in width.
Suitable for your workstation?
The seat has a width of 455 mm and a depth of 410 to 475 mm. The load capacity is 110 kg. The chair is finished in black/grey, with a black plastic base and upholstery of 100% polyester. Please note: optional casters for hard floors (Hartbodenrollen, article number 70699952) are an accessory and not included in the delivery scope.
