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.
