Aeris Office stool Swopper 101STBKBK black/red, with glides

The Aeris Swopper is the classic among office stools and features 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 body's strong muscles support the back, resulting in a sense of well-being instead of tension.
