Increase the comfort of your sitting time with the Koplus Tonique everyday ergonomic task chair. 

• Determines your correct seat adjustments by automatically adjusting the tension according to the weight and height of the user
• Seat back fits the natural curve of the sitter to provide full support 
• Back mesh increases in density from top to bottom in order to provide a smooth graduation of tension to the area requiring the greatest support (back and spine)

• Auto-balances to help you sit in comfort - using the Tonique self-regulating mechanism
• Tilt allows four locking positions so that you can choose the right position for you. If you prefer the chair to move when you lean back, you can use it 'unlocked'
