Movement is quality of life.

Dynamic sitting means healthy sitting. Normal office swivel chairs give your back only a limited amount of supported movement. The duo-back balance® gives a new freedom to you and offers all functions of a modern office swivel chair – with innovative ergonomic engineering.

Duo-Back Balance

The unique balance effect is covered by a world-wide patent application and meets the NPR standard 1813 and EN-1335.

Evolution is progress

The unique balance function of the duo-back balance® follows any movement of the back. This creates a pleasant “balanced” movement of the backrests to both sides. Due to the two-part backrest the spinal column is supported without exerting pressure. Furthermore the balance effect of the backrest allows for a light torsion of the spinal column and makes for an improved nutrient supply of the spinal disc.

Duo-Back Balance

Adjustment of the seat

The NPR-1813 version of duo-back balance® is far beyond the requirements of EN-1335. The duo-back balance® is characterised by an ideal range of adjustment. The seat height is freely adjustable from 400 - 510 mm (EN-1335) or from 410 - 550 mm (NPR-1813), so that the duo-back balance® fulfils all requirements. The seat is depth adjustable through 100 mm from 380 - 480 mm and inclinable through 4°.
