Revolver Stool is a practical stool from the Danish brand HAY designed by Leon Ransmeier. The chair is made of steel and aluminum and comes in the three colors Black, Red, and Sky Gray. The Revolver Stool has a swivel seat that can be rotated up to 360 degrees, which is a testament to both versatile and functional design in one. The narrow seat with curved edges is offset by its angled, straight legs, creating a silhouette that offers limitless applications. The Revolver Stool is suitable for both private and public environments. The series also includes the Revolver Bar Stool and the Revolver Table.
