Description
Overview
Cornet is a bar stool designed by Jonas Trampedach for HAY. A round solid oak seat sits on a slender steel base, and HAY says the stool comes in two heights with a choice of wood finishes for the seat and chrome or powder coated colours for the legs.

Construction
The frame uses a steel-tube technique that HAY says is borrowed from bicycle racks. The variant pages list a steel frame and footrest in one finish, a seat of solid oak and standard gliders.

Story
A technique seen in the street
Trampedach tells HAY that he first noticed the steel-tube technique on bicycle racks around Copenhagen and then found it in hand tools, plumbing and ventilation systems. The technique was the starting point of the stool, and the rest of the object followed from its logic.
Working with Rolf Hay
According to Trampedach, Rolf Hay asked one day whether they should do a project in steel. They agreed to explore this technique and sketched on blank paper before the stool was chosen from several typologies.
