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. With all these features, Marva fully complies with the most stringent standards for office swivel chairs in accordance with EN 1335.
