UNO Chair Comfortable Seating Features:
1. Back Automatic Supporting (BAS) System
BAS System gives your back comfortable support.
For users, when you work and sit for a long time, the most stressful part of your body is your waist.
Long-term stress can lead to lumbar disc herniation and other occupational diseases.
The backrest has two parts with intelligent elastic rotation device on the connection of its parts.
The upper part can rotate within 10° and the lower part can rotate within 15°, without any adjustment, to automatically fit different people's weight, shape, sitting posture and tilting angle.
Most importantly, it will help your back always attach on the chair backrest, give you a full and comfortable back & waist supporting.
2. Double Spring Paddle Shift Wire Control Mechanism
It contains over 90 individual components, including gears, linkages, shafts, blocks, shields etc., precisely assembled under 9 steps.
This mechanism could adjust 15 levels under 33 degrees tilting angles by simple operation, while normal chairs have only 4-6 levels under 28 degree.
It is much more safe and offer user a incredibly smooth backrest recline experience.
3. Seat Height Adjustment
The seat height can be adjusted with the lever in the right armrest.
4. Reclining Position Lock
