Next time you find yourself with too many guests and too few chairs just combine the two. The Strap-On Chair by designer Annika Schmidt affixes easily to the human body by way of leather straps, and the two working models at the moment place the chair along a person's back or chest. You may want to stick to the back model as it looks far more sturdy.
You won't see the Strap-On Chair at Ikea anytime soon — it's an exhibition piece, not a furniture concept. Still, lop the legs off one of your chairs at home, get some leather, and then you're in business.
