Milan-based designer James Irvine has designed an I-beam shaped stool for Italian design brand Discipline to be exhibited during Helsinki Design Week this month.

The name Centanni derives from the hope that the durable design can last 100 years.

Created using larch wood and oak, the design uses no glue or screws. Instead sections are slotted together using a system of tenons and wedges.

Italian brand Discipline launched in Milan this year.  The Centanni Stool will be available at the end of September and Helsinki Design Week runs from 6-16th September.
