Using your Nardi Trill Bar Stool is easy. Just place it wherever you need a seat, whether it's indoors at your bar or outdoors on your patio. Since it can support up to 300 lbs, it's suitable for most people. When it comes to stacking, simply stack the stools on top of each other for easy storage when not in use. For safety, make sure the non - slip foot pads are in place. If they get worn out, you can easily replace them. To keep your stool looking great, clean it regularly with a mild soap and water. Avoid using abrasive cleaners as they might damage the matte finish. Since it's made from UV - resistant and rust - proof materials, it can withstand outdoor elements, but it's still a good idea to store it indoors during harsh weather to extend its lifespan.
