OUTPERFORMS COMPETITION
The patented dorsokinetic mechanism that features in this chair means the backrest is attached at only one point meaning dynamic movements from side to side can support the user in everyday motions.
support where you need it
All models in the black dot series have either a classic or a transparent mesh backrest, and they dazzle with their advanced technology. The backrest is connected by a flexible joint at a single point, unlike other chairs that are stiff. The Sedus black dot is flexible and backs you up, even when you twist or turn sideways

TECHNICAL SPECIFICATION
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
• Shaped foam (polyurethane foam)
• Width 470 mm, depth 420 mm
• Optional sliding seat with seat depth 400 - 460 mm
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 gas lift for infinitely variable height adjustment 390 - 520 mm
• Optional gas lift 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

MECHANISM
• Similar mechanism with tension control: balanced force curve due to coordinated spring concept
• Seat and backrest move completely synchronised with the body
• Synchronicity relationship between seat and backrest 1:2.7
• Adaptation to different user weights enables sensitive latching of the rapid adjustment mechanism (leaning pressure 450 - 1200N and 550 - 1500N (stronger spring) [10N = 1 kg])
• Backrest inclination to approx. 32°, can be locked in virtually continuously variable manner (11 different settings)
• Permanent back support even when the backrest is inclined backwards at a wide angle, due to uniform force distribution of the mechanical springs
• Optional seat tilt adjustment (+0°; -2°; -4°), less pressure against the thighs without the user sliding out of the seat pan
