Our Shop Stools are made in Chicago and perfect for your garage or workshop. Since you are buying a shop stool, I assume you know about construction. We use heavy-duty commercial upholstery vinyl for the seat. There is a top piece and a side piece, and they get sewn together using size 69 nylon bonded thread. Under the vinyl is a layer of medium-density foam about 1.5 inches thick. Below the foam is a 3" tall cylindrical box with a 14.25" diameter. Our version of this style bar stool is much better than the imports. You won't go wrong when you buy American Made!
