Installation / Usage Tips
Unbox all components and lay them out on a soft surface to avoid scratches. Follow the included instruction manual—assembly typically takes about 10 minutes. Inflate or deflate the lumbar airbag to your preferred firmness before long use. Adjust the seat height to ensure knees are at a comfortable 90° angle and the headrest supports the base of your skull. Tighten fasteners snugly but avoid overtightening.
