Product description

String is a quintessence of ergonomic solutions and a simple form. It was created with a view to a comfort and good physical conditions of users. Thanks to its form, light innovative structure as well as possibility of adjustment all the parameters it gives the guarantee of a healthy and secure seating. This is an advanced chair in terms of technology that ideally adjusts to the shape of users body thanks to a perfectly profiled backrest covered with an elastic and flexible membrane. Combination of this element with a synchronous mechanism gives a sense of maximal comfort and allows of socalled dynamic seating that relieves the spine during a long staying in static position. The wholeness is complemented by an attractive colouring of membranes. Thanks to this String goes together perfectly with a neutral but also with a little bit more aggressive space of modern offices.

The String collection is supplemented by conference chairs on legs and cantilever frame which thanks to application of a perfectly profiled membrane backrest provides seating comfort during long business meetings.
