Black Dot Ergonomic Task Chair

Similar mechanism with spring-force adjustment
for dynamic sitting

• Balanced force curve thanks to coordinated spring concept
• Seat and backrest move completely synchronously with the body
• Adaptation to different user weights is enabled by individual adjustment of the spring force (450 to 1200N and 550 to 1500N [10N = 1 kg] pressing force)
• Recommended for user weights up to: 130 kg
• Backrest inclination up to 32°, can be arrested at many positions (11 different positions)
• Permanent back support due to mechanical springs even when body tilted very far back
• Optional seating surface adjustment to three different positions (0°; 2°; 4°), for less pressure on upper thighs without the person sliding out of the hollow in the seat
• Synchronism ratio of seat to backrest approx. 1:2.7

Patented “Dorsokinetic” in the backrest

• For considerably enhanced freedom of movement, the backrest supports and the backrest are connected to each other by an articulated dorsal-kinetic feature.
• Due to the articulated dorsal-kinetic feature, the backrest possesses an additional degree of freedom of 15° for backward movements and 8° for sideways movements of the upper body.
  
  

Seat height adjustment

• Sedo-lift mechanism III: Full suspension of the body weight even in the bottom seat position due to pneumatic locking, practically wear-free, no failure or gas spring replacement. The patented mechanism is guaranteed for 30 years.
