Revolver Bar Stool is a functional bar stool designed by Leon Ransmeier for the Danish brand HAY. The bar stool is available in two heights and is available in Black, Red, and Sky Gray. The seat and foot of the Revolver Bar Stool are swivel and can rotate up to 360 degrees. The seat is narrow with curved edges to add extra comfort, while the footrest and base provide total support and stability. Thanks to the rotating function, the Revolver Bar Stool is a playful and practical chair that can be used in a variety of ways, both in private and public settings. The collection also includes the Revolver Stool and the Revolver Table.
