The "Universal" chair by Joe Colombo from 1967 is the first fully plastic chair in the world for adults, produced in ABS.
Its structure, with a single element seat-back and pressure-applied legs, is reminiscent of the Zanuso and Sapper children's chair. The hole, very complicated to make, is the detail that characterizes it aesthetically and is functional to an easier grip of the chair. Another aspect that makes the creation of the “Universal” difficult is represented by the choice of material, which must guarantee resistance even to the high humidity levels of the outside. For this reason, with the advancement of technologies, Kartell finds itself having to use different materials that are increasingly durable. The chair is produced until 2012 when it comes out of the catalog after 45 years.
