What does an office swivel chair with Sitness technology do?
This office swivel chair combines ergonomic sitting with active movement throughout your working day. The integrated Sitness joint in the seat keeps your pelvis and lower back moving, even during long periods of sitting. This helps to improve your posture and prevents stiffness.

Why choose the Punktsynchron mechanism?
The Punktsynchron mechanism provides a natural movement in which the backrest and seat move in sync around a single pivot point. This supports your spine better than standard mechanisms and keeps your vertebral column in the correct position. The stepless seat height adjustment lets you find the perfect working posture between 450 and 550 mm in height.

What about comfort and upholstery?
The seat has a bowl shape that supports your pelvis, while the backrest with laminated cushioning offers extra comfort. The 100% Trevira CS upholstery is flame-retardant and durable. With seat dimensions of 470 x 470 mm, the chair offers ample space for comfortable sitting, and the 580 mm high backrest supports your entire back.

Practical considerations for use
This chair is suitable for users up to 110 kg and comes as standard with armrests for extra support. For use on hard floors, you can order optional hard floor castors (article number 70699952) to protect your floor and move smoothly.
