Marva Net

Swivel chair with mesh backrest and concealed ergonomic functions.
Design: Mathias Seiler
The rounded mesh backrest gives Marva a transparent, lightweight appearance. It is also very comfortable, as it adapts to the contours of the back. The seat technology is almost entirely concealed within the round, generously-proportioned seat, making it virtually invisible. Despite this, Marva Net still has all the functions and adjustability you would expect of an ergonomic swivel chair: synchronic mechanism with automatic spring tension adjustment for dynamic sitting, precise adjustment of the seat, lumbar area, engageable negative seat tilt for upright sitting and multiple armrest settings.
