Description WithME embodies the maximum of economic reduction and minimalistic design for a full-featured swivel chair with self-weighting synchronous adjustment. The model basically consists of three plastic components: the seat, the backrest and the armrest with its supporting structure. WithME does not require a mechanism with metal springs to achieve a comfortable motion sequence. The standard system is replaced by the intelligent patented arm-bar, whose lower crossbar acts as a torsion spring. All components together make up a mechanical system with the advantage of an airy transparent reduced chair base. Thanks to the use of lightweight components, WithME remains extremely light. All components can be easily dismantled and are easy to recycle. Design and technical concept: Design Ballendat.
