The "swopper" supports and encourages alternating postures and movements, ensuring the user is always sitting in the proper position, while strengthening their abdominal and back muscles. Keeping the spine and inter-vertebral discs fit, the "swopper" stimulates circulation and prevents wear of the joints.
Barefoot Studio, a body management company based in Wales, is now the sole UK agent of Aeris' the "swopper": the first seat of its kind designed to adapt to movement in every direction - forward, backward, sideways and vertically, virtually eliminating backache and tension.
The "swopper", designed by German engineer Josef Glockl and his Physical Therapist wife Dorothea Prodinger-Glock, has won awards for function and design, including the 'Seal of Quality' from the Healthy Back Action Committee and 'Best for Innovation and Gold Award' in the office chair category.
