  • Seat recline: Pull the cable control regulator backward, lean back slightly with your back to achieve recline; after reclining to a suitable angle, reset the cable control regulator to the middle position to lock the angle; when returning to the upright position, pull the regulator backward again, lean forward with your body, and the backrest will return to the upright position and be fixed when the regulator is also back in place.
  • Footrest function: Pull out the footrest and flip it upwards, and place your feet on it for use.
  • Seat depth adjustment: Pull the cable control regulator forward, move the seat cushion to a suitable position, and then reset the regulator to the middle position to lock the seat depth distance.
  • Lumbar support adjustment: Hold the lumbar support connector and move it slightly upwards to raise the position of the lumbar support, which is a circulating gear; when the lumbar support control rod is in the upper gear, the front-back position is locked; when it is in the lower gear, the front-back adaptive lumbar support is unlocked. After finding a suitable position, pull the control rod upwards to fix the position. When reclining, the lumbar support will automatically slide down for support.
