Operating Instructions

Height Adjustment:

To adjust the chair's height, locate the lever on the right side, beneath the seat. While seated, pull the lever up to lower the chair. To raise the chair, stand up and pull the lever up. Release the lever at your desired height to lock it in place.

Tilt Function (Rocking Style):

The chair features a 90°-120° tilt tension for comfortable reclining. To activate the tilt, pull out the adjustment lever located on the left side, beneath the seat. To lock the chair in an upright position, push the lever back in. The tilt tension knob, located at the front of the mechanism, can be rotated to adjust the resistance of the recline.
