Seat inclination
The seat inclination can be fluidly adjusted by up to 20° by means of a sturdy, user-friendly eccentric quick-release fastener. Once set, the position is firm and steady.
Seat shapes
1. Standard shape "F" with rounded front edge
2. Curved shape "S" with rounded front edge and spinal support
The rounded front edge forestalls leg fatigue and circulatory problems. The back support forestalls damage caused by poor sitting positions.
Seating surface: width x depth = 44 x 42 cm.
Backrest adjustment
The backrest inclination is adjusted by means of a TÜV-tested safety pneumatic spring with release lever with break-proof bearing. Thanks to extreme lift of the pneumatic spring, the backrest provides support even when seated in the foremost seating position. The removable backrest can be adjusted in height fluidly and silently by means of a knurled screw. The position set is firm and steady.
Seat design
The seat, mounted on elastic rubber elements, is crafted from robust multi-ply beech wood and features ventilation perforation holes. It has 4 cm of high-quality breathable foam rubber cushioning.
Backrest
The backrest pan is made from multi-ply beech wood and covered with a synthetic material covering. The backrest cushioning is a 3 cm thick layer of high-quality breathable furniture-grade foam rubber. Its moveable mounting on back upright allows it to adapt perfectly to the user's posture.
Fabric cover
In January 2014 we started to supply our chairs with a new and better fabric of flame-retardant Trevira® CS with abrasion resistance of 100,000 rubs (Martindale).
Standard colour: anthracite (flecked with grey, insensitive to dirt)
From a distance of 2 - 3 m on the difference between old and new fabric cannot be discerned any more.
Fabric colours
2 or 3 coloured melange: red, wine-red, green, blue, anthracite (standard)
solid coloured: black
Other colours and fabrics are available on request. We recommend fabrics that are 2 or 3 coloured, as they are insensitive to dirt.
