The included walnut wood seat is constructed of sturdy wood and designed for indoor use to enhance your dining space. The seat conveniently screws onto the chair, which is practical for indoor usage, but can still be removed to retain the outdoor versatility of the metal chair. Wood is a timeless, classy aesthetic, and it will impart an upscale look to your bistro, cafe, or restaurant. The included hardware makes installation straightforward. With clearly defined drill hole notches, you can have your new seat covers ready in no time!
