System 77 office chair

System 77 provides everything ergonomic seating of the next generation has to offer - as standard, without any compromise. Man is not made for long periods of sitting. System 77 "takes special care" of the problematic zones and weak points. With the innovative AIR-GO-PUR seat, a milestone is set as regards ergonomics and comfort. The unique combination of visco-elastic foam and Air-Control-Inlay emphasises the technological lead of System 77.

The range 7780 is a lighter design version with small backrest, especially designed for the lightweight user. All ergonomic benefits are, of course, present and may be adapted to your individual needs and situation at work. System 77 improves your seating posture and supports your movements.

The 3D-armrests with their multiple adjustment options reduce the strain on arms, hands, shoulders and neck. An individual adjustment adapted to each activity is easily possible by pressing a button. The armrests are available in three versions: covered with fabric or foam.

Almost all of the weight of the upper body is supported by the ischial tuberosity. An increasing feeling of pressure and tension spread in the buttocks and pelvic region, cause discomfort and pain. Reduced venous activity leads to lower back pain syndrome, among other ailments. In this case, pressure is exerted on nerve exits and arborisation in the lumbar region due to venous obstruction in the spinal canal. Within a brief period of time, sitting becomes torture. The innovative AIR-GO-PUR® chair provides for optimum pressure relief in the buttocks region. A double-chamber cushion filled with air helps users shift their weight and provides for more easier rocking motion in the pelvic region. This is transferred to the lumbar vertebrae and furthers circulation and the metabolism. Visco-elastic foam provides for pressure relief and imitates the individual shape of the body with elastic support at pressure points. The combination of these innovative technologies truly sets new standards in regard to seating comfort.
