This stool, created by designers at the Italian design studio MID, is put together by a wedge, driven right through its heart. Well, through its centre, at least — like the old-fashioned axel with which it shares a name.
The natural Ash legs of the Axel Stool, which look as though they could have been slit from a single log using a heavy axe, are fixed in place with a matching wooden cross that has to be driven in with a mallet. Get it right, and five elements — four legs and the wedge — should fit pleasingly flush with the table's metal surface. Get it wrong, and you'll have an uncomfortable spot beneath your butt — a less literal, but perhaps more noticeable, wedge between you and it. The stool will be on show during Milan Design Week in April. [MID via DesignBoom]
