Executive chairs usually announce their engineering: exposed plates, visible arms, a black plastic housing under the seat. Musa Chair takes the opposite decision, and ICF states it plainly — all the structural elements and the tilting mechanism are hidden inside a shell of flexible foamed polyurethane, available in premium fabric or leather. The steel tubing and sections that carry the load are there; you simply never see them.
What is left to look at is a shape: closed armrests that flow into the seat, a die-cast aluminium ring that draws the outline, seams that follow the form rather than interrupt it. It is a quieter proposition than the usual director's chair, and a more durable one, because the parts that get scuffed on an exposed mechanism are simply not exposed. Three backrest heights — Low Back for the meeting version, High Back, With Headrest — cover the room hierarchy without changing the language. La Mercanti supplies the collection internationally, with samples reviewed before the order is confirmed.
