Using these stools is a breeze. First, assemble them following the instructions and hardware provided. Once assembled, to adjust the seat height, simply use the black side lever on the side of the stool. Pull it up or push it down to raise or lower the seat to your desired height between 24 and 30 inches. The swivel function allows you to turn around easily, so take advantage of that for better comfort and interaction. When it comes to maintenance, clean the faux - leather seats with a soft, damp cloth. For the metal base, you can use a mild cleaner. Avoid using abrasive materials as they might scratch the surface. Also, keep in mind that the color might vary a bit from the images, so don't be surprised if there's a slight difference. If you have any questions or run into any issues during assembly or use, feel free to reach out to our customer service.
