KOS Extend M 100 Chair | Ergonomic Office Chair

This office chair is engineered for peak precision and performance. Its intelligent design will optimise your posture and breathing, so you will always feel alert and preform at your best. 

The movement of the chair is based on the principles of upright posture and active sitting.   This ensures that your body receives the variation and support it requires as you move.

• Movement And Support:
• • The Extend M Office chair offers a backrest and seat angles that move simultaneously when you change your position.  As the chair’s basic settings do not change, this helps you to do more and perform better.
  • The Extend chair is also available in other models, with a larger back rests and with a back angle adjustment.
  • The backrest on the Extend M is equipped with a ”Tvedts” cushion, providing superb support for the whole upper body.  The shape of the backrest encourages movement and the height is adjusted with the simple push of a button.
• Adjustability:
• • The controls for the height and depth of the seat are all conveniently located on the right-hand side of the chair.  The correct height improves blood flow in the legs while the correct seat depth provides greater comfort and support.  The tilt mechanism is infinitely adjustable, with a smooth action that can be locked in any chosen position.
  • Dynamic seating means the chair follows your every movement regardless of working position providing complete support, enabling you to always sit correctly and breathe properly.
    
    

The seat provides excellent support and has a waterfall edge to reduce pressure on the underside of the thighs, aiding circulation.  It is also designed to keep you positioned in the middle of the seat, even when it is inclined forward.

The resistance of the tilt mechanism is simply adjusted according to body weight and height. This allows this office chair to follow your movements without the need to exert muscular force to push the chair into new positions.

Armrests are optional but are recommended since they provide relief for the shoulders.  They are adjustable in width and depth with a rotating function.
