Using this Gibraltar performance stool is a breeze. To adjust the height, just lift the hydraulic lever until you reach your desired height. When you're done using it, separate the base from the seat and backrest and collapse the base for easy storage and transportation. For safety, don't exceed the maximum weight capacity of 250lbs. Keep the stool clean by wiping it with a soft, damp cloth regularly. Avoid using harsh chemicals as they may damage the leather - like vinyl seat. If you notice any loose parts, tighten them immediately to ensure long - lasting use.
