This unusual swivel chair features a reclining angle of up to 45 degrees; a value which, when combined with a dorsokinetically suspended backrest, is achieved by no other chair on the market. The flexible backrest connection ideally supports the back during all rotating and lateral movements.
Dorsokinetic mechanism
With the flexible backrest connection, open up supports you at all times. The backrest follows your every movement. Sideways. Backwards.
Lumbar support
Height-adjustable strain-relief for the lower back. To ensure that the backrest fits perfectly to your back.
3D armrests
Comfort that adapts. In every direction. In Soft-touch, with leather upholstery or gel insert.
