Modern Bar Stool BS-08

Material: The seat and back are made of white vinyl or PVC. While cannot be confirmed from the image for sure, vinyl or PVC are common materials for these stools because they are easy to clean and water resistant. The base and legs are made of black metal.
Style: The simple design of the stool with its white seat and black base would likely complement a variety of décor styles, from modern to industrial.
Backrest: The stool has a curved backrest that should provide some lumbar support.
Seat: The seat is padded for comfort.
Footrest: The stool does not have a footrest.
Swivel: It is not possible to tell from the image if the stool has a swivel mechanism, but many bar stools do.  A swivel mechanism allows the user to rotate on the stool without having to move the entire stool itself.
Wheels: The base has four black caster wheels, which makes the stool easy to move around.
Adjustable height: It is not possible to tell from the image if the stool has a height adjustment mechanism, but some stools with this design do.
