This office chair supports your back during long working days thanks to the special disc seat with knee tilt and padded backrest. With point synchro mechanism and stepless seat height adjustment, you can effortlessly adjust it to your posture.
When do you choose this product?
When do you need a disc-friendly chair?
This office chair has been specially developed for people who sit a lot and suffer from back problems or want to prevent them. The special disc-friendly seat with knee roll relieves your lower back by keeping the pelvis in a natural position. This prevents tension in the lumbar spine during long working days.
Why choose this compact size?
With seat dimensions of 45 x 46 cm, this is a compact office chair that is suitable for smaller workspaces or home office corners. The seat height is infinitely adjustable from 45 to 55 cm, so you can perfectly adjust the chair to your height and desk height. The 110 kg load capacity makes the chair suitable for most users.
How does the point synchronous mechanism work?
The point synchronous mechanism ensures that the backrest and seat move together in a natural ratio when you lean back. This encourages a dynamic sitting posture and prevents you from remaining in the same position for too long. The padded backrest, 65 cm high, provides support for your lower and middle back.
Practical adjustments for your workspace
The chair is supplied as standard with carpet castors, ideal for use on fixed floor coverings. Working on a hard floor? You can optionally order hard floor castors (article number 70699952). Optional armrests are also available (type S2, article number 77240244) for extra arm support while typing.
