5Waves 

The main element of the 5-Waves chair design is its innovative injection-molded shell with dynamic
seating comfort – supporting the body without restricting itsmovement.
5-Waves’ shell has 5 zones, or “waves”, each with its own distinctproperties:
the first “wave” provides rigidity – it is purely structural;
the second “wave” transitions between the structural zone andspringy zones;
the third “wave” o ers support for the pelvis and lower back;
the fourth “wave” provides springy dynamic support;
the fifth “wave” is an elastic outer zone reducing unnecessary pressure on the soft tissues of the body.
