As the name infers, bar stools with arms have arms and a back. Kitchen bar stools with arms are comfortable but do take up more space at the bar counter. The seat height of a bar stool with arms is 30 inches from floor to the top of the seat. This 30 inch measurement is called 'bar height'. Bar height stools with arms come in a variety of styles and manufactured with metal, wood or a mix of the two. Seats and backs of a bar height bar stool with arms are available in wood, metal or upholstery.
