black dot
Swivel chair
Innovative technology for maximum well-being
Whether classically upholstered or with a transparent mesh backrest – all models in the Sedus black dot series impress with their sophisticated technology, perfect individual user customisation options and absolutely smooth functioning. What’s unique about Sedus’ patented dorsokinetic mechanism is that the backrest is attached at only one point by a flexible joint. Whereas other chairs are rigid, Sedus black dot is dynamic and supports the back, even when swivelling or turning to the side.
Classic upholstered comfort and transparent lightness
The sophisticated upholstery system and the first-class finish emphasise the high quality of this family of chairs, and contribute towards its longevity. With its airy membrane backrest, Sedus black dot net is extremely slim and light. The covering ensures optimal pressure distribution of body weight. The patented Sedo-Lift mechanism also contributes towards excellent seating comfort. It is used to adjust the seat height easily, continuously and free from wear. At the same time, the Sedo Lift mechanism guarantees a soft, pleasant suspension regardless of the chosen seat height.

| black dot |
|
| User weight | • Recommended for user weights up to 130 kg |
| Seat | • Anatomically shaped seating surface with pelvis support, seat hollow and rounded front edge of seat |
| Seat height-adjustment | • Sedo-lift mechanism III: complete cushioning of body weight, even in lowest seating position, no compression of the spine when sitting down provided by hydraulic interlock, completely free of wear and tear, mechanical failure or gas lift replacement, height adjustment between 420 - 530 mm • Optional gaslift for infinitely variable height adjustment 390 - 520 mm • Optional gaslift for counter design with footring |
| Base | • Aluminium base, powder-coated, black, white aluminium, white or polished aluminium • Optional plastic star base (glass-fibre reinforced polyamide), black or light grey • Hard or soft castors with 65 mm diameter • The backrest support always matches the star base, so a swivel chair with a polished star base automatically comes with a polished backrest support. |
| Backrest | • Integrated height-adjustable (80 mm) • Due to the dorsokinetic joint the backrest has an additional degree of freedom of 15° for backward movements and of 8° for lateral movements of the upper body • Backrest made of polypropylene • Upholstery thickness 50 mm • Back of backrest partially upholstered for pleasant feel to the touch • Side ends of the upholstery made of air-permeable material in different coloured knitted spacer fabric (black) • Optional for versions with the high backrest: neck support with height (80 mm) and tilt adjustment (25°), for fabric versions made of black vinyl; for leather versions, neck support in the selected leather • Optional coat hanger in conjunction with neck support |
