Features:

  • Equation's innovative back technology allows for minimal adjustments and maximum support. Just push the buttons on the lower back frame to push or pull the lower back closer or further away from you. Adjusts to 3 back angle settings for the perfect sit: 103.5° (neutral), 105.25° (position 1), and 106.25° (position 2).
  • Synchro Tilt mechanism is designed to coordinate the movement of the seat and backrest at an optimal ratio, ensuring continuous support throughout the recline range while maintaining lower body alignment.
  • Weight Activated mechanism utilizes the user's weight to adjust to a comfortable sitting position and intuitively responds to each individual's torque requirements.
  • Integrated seat slider (included with both mechanisms) allows for easy and smooth seat depth adjustment
