EWS.3 Cantilever Chair

Dynamic seating in a new dimension.

The Cantilever Chair EWS.3: even more agile, bouncy, comfortable. For a strong back and sustained concentration.

Even more so than conventional, free-swinging chairs, the EWS.3 promotes healthy dynamic sitting. The tubular frame, which is open at the front, is made of a highly elastic high-tech steel. In combination with the bouncy 3D Seat Shell, the EWS.3 achieves a vibration behaviour that defines a new seating quality.

When sitting in a forward position (e.g. when working at a table), the seat also tilts forward. This creates an open seat angle that relieves the lumbar vertebrae. When leaning back in a relaxed position, the chair swings backwards, optimally supporting and relieving the back. The cantilever chair reacts gently and resiliently to every shift of weight and thus keeps the body constantly in slight motion. Instead of remaining in one position, the sitter is encouraged to change his or her posture frequently.

The result: the muscles are stimulated and tension and back problems are prevented.

Extremely robust and stable. Comfortable to carry.
Easily stackable.

Seat Shell optionally made of polypropylene with closed, easy-to-clean surface or of naturally lacquered beech plywood. Also available with seat pad on request. Seat height 46 cm.

Tested safety: GS-certified.

So every backpack has the perfect hold.

Thanks to the slightly downward curved backrest, backpacks and bags cannot slide down. Thanks to the floor glides that are pulled far back, the Cantilever Chair EWS.3 stands securely and stably even when loaded with heavy school bags and cannot tip over.
Nothing disturbs the lesson, the floor remains clear and no one trips over bags lying around.

For a strong back and sustained concentration.
