Using your new office chair is a breeze. First, adjust the seat height to your liking by using the height adjustment lever. You can set it anywhere from 19.25 to 22.75 inches. Then, sit back and enjoy the comfortable thick foam padding and breathable PU leather. If you want to relax and relieve some lumbar pressure, use the tilt function. The 360-degree swivel seat and smooth-rolling wheels allow you to move around your workspace easily. As for maintenance, just clean the chair regularly with a soft, damp cloth to keep it looking its best. Remember not to exceed the maximum load of 264 lbs to ensure the chair's long-lasting performance.
