ronan + erwan bouroullec present the ‘stampa’ armchair; an aluminium seat designed to assume a delicate sturdiness well attuned to the passage of time, during the 2015 salone del mobile.

conceived in collaboration with kettal, ‘stampa’ is produced using a combination of several aluminium manufacturing techniques. injection-moulded rings connect the stamped seat, back, and hydro-formed legs–a construction which adds overall strength to the design. the calyx-shaped shell is characterized by a series of organized holes carefully punctured through the surface–using a process employed for perforating metal sheets–which breaks the solidness of the object without harming structural integrity. this approach results in a delicate shape that recalls the sensation of textiles.

the armchair is available in two versions and finishes: perforated, or planed with powder coated, or anodized treatment; with an additional cushion available. dry assembly allows the ‘stampa’ chair to be stacked easily during transport or stocking. all versions are suitable for interior or exterior use.
