m4

The specialty of the swivel chair family M4 is the mechanism formed like a bridge.
This bridge is the movable part of the mechanism that integrates also the seat- depth adjuster and enhances the flexibility of the mesh upholstery. It also integrates the levers for the seat- height adjuster and the seat- inclination adjuster, a brilliant solution that offers a maximum reduction combined with optimal efficiency of the seat – and back mechanism.
The mechanism is surrounded by a polished radial back carrier. The side arms of the carrier are also height- adjustable. So we didn´t simply fasten height adjustable arm- rests to the mechanism or the seat, but the arm rests are part of the back- carrier.
