Using this Lemi pedicure stool is a breeze. First, adjust the height of the stool using the gas - pump to a level that's most comfortable for you. Then, sit back and start your beauty treatments. When it comes to maintenance, wipe the stool regularly with a clean, damp cloth to keep it looking good. Avoid using harsh chemicals as they might damage the plastic or foam. If you've chosen the aluminum base, check it periodically for any signs of rust or wear. And remember, the structure and gaslift are covered by a 2 - year warranty, while the underformable foam has a 5 - year warranty, so if you encounter any problems within these periods, don't hesitate to reach out for support.
