Aeris Office stool Swopper 102HBSTBK black/blue, with castors

The Aeris Swopper is the classic office stool, featuring not only an aesthetically pleasing design but also the genuine Aeris 3D technology. It follows the movements of its sitter in all three directions: forward, sideways, and even vertically. The effective up-and-down movement, known as vertical swinging or "swopping," mimics walking or running, nourishing and relieving the intervertebral discs. Instead of a backrest, the strong muscles of the body support the back, leading to a feeling of well-being rather than tension.
