Physix is an office chair designed by designer Alberto Meda for the Swiss brand Vitra. Physix was presented at the Stockholm International Fair in 2013 and is available in several versions. Physix is also height-adjustable. The office chair is based on the idea of creating a seat that follows the body by stretching a single textile mesh between the two sides. Using materials of the highest quality, Physix has been designed with an interaction between three elements to create a new seating experience: a flexible frame construction, an elastically knitted seat and a stabilizing mechanism.
