Jig is a bar stool with a simple and angular design, conceived by Chris Martin and designed by the Mass Productions brand. This stool is available in various finishes and in different coverings in categories C and C +. Jig is produced in two sizes. Jig is made solely from simple steel tubes, inserted into a jig, which are welded together to create a new design for an old typology. With Jig, designer Chris Martin chose instead to cut the tubes directly and let them hold their shape, which gives the stool a sharp, pointed look. Jig was originally made for public environments, with a focus on comfort but can also be used for living rooms.
