Varier Variable – The Original Ergonomic Knee Chair

The Varier Variable is the classic knee chair. Designed in 1979 by Peter Opsvik , this chair is known worldwide as the original design that took dynamic sitting to a new level. With its timeless design and proven ergonomics, it's the perfect choice for those who take their posture and well-being seriously.

Promote an Active Sitting Posture

The Variable encourages natural, continuous movement . The knee support automatically guides the hips and pelvis into an open, upright position. The result? Improved posture , relaxed shoulders , and a stronger lower back .

Advantages at a glance:

  • Relieves pressure on the lower back

  • Promotes an upright posture

Fluid & Dynamic Design

Thanks to the curved wooden runners, the chair moves with your body. Lean slightly forward or backward and experience the unique balance and active support . Whether you're writing, reading, or concentrating at a desk, the Variable keeps you moving.

Simple, but Well Thoughtful
