The aluminum supports, placed along both sides of the chair, are machined with the advanced technology of CNC .This process allows to model the aluminum alloy profile with extreme precision. The aluminum is further given an electrochemical treatment to harden the outer surface that gives the alloy more resistance to nicks and scratches as well as a brilliant silver finish.
The mechanical heart of the chair is made up of a rocking mechanism that applies to one’s back, a soft and constant force. This bilateral pressure is obtained by the use of two springs that work in torsion incrementally, therefore transmiting these forces to the lateral supports.
The under-structure is made up of six distinct mechanical parts, all of which are constructed in stainless steel with the highest of mechanical precision in order to avoid creaking
The backrest has an angular movement of thirteen degrees at the end of which a sturdy limiting device blocks over rotation and positions the center of gravity at the base, thus avoiding dangerous inclinations and instability
The extreme strength and dimension of the mechanical parts of this chair are needed because about 50% of the torsional, static, and dynamic loads caused by a person sitting in the chair are directly applied to the structure.
