Bike Seat Stool
This simple stool evokes the styling of Italian designer, Achille Castiglioni. His Sella chair is a bit out of reach for most of us — especially at £336. Designer, Aldo Parise, created this chair using Everyday bikes retro cruiser saddle and pieces from Home Depot. The base is lemon oil stained poplar. In all it adds up to $40 of material.
