Using these stools is easy. To adjust the seat height, just lift the leveler on the side. You can raise it up to 30.83” or lower it to 22.72”. The stools swivel 360 degrees, so you can turn around easily. When not in use, lower the seats and tuck them under the breakfast or wet bar thanks to their backless design. Assembly is minimal, and you can put them together without much hassle. Remember, this product can expose you to certain chemicals, so be aware of the Prop 65 warning. For maintenance, wipe the black PVC seats with a damp cloth. Keep the chrome parts clean to maintain their shine. If you need replacement parts, you can request them from the manufacturer within 60 days of buying the stools.
