The key feature of the chairs from the 5-Waves product range is their injection-moulded shell which supports the body without restricting its movement. These chairs have five different zones or “waves”, each with its own distinct properties. The first wave provides rigidity and is purely structural. The second wave connects the structural with the elastic zones. The third wave supports the pelvis and the lower back while the fourth provides dynamic elasticity. The final flexible fifth outer zone reduces unnecessary pressure on the body.
