Somewhat ironic given their name, but the Shakers never had to deal with subways rattling their walls, and their system of hanging chairs on wall-mounted pegs served them well. Netherlands-founded, Eugene, OR-based Studio Gorm (remember their Flow Kitchen?) takes that idea further with their Wood Peg furniture line, a series of benches, stools and tables that all break down flat and can be stored on a rail on the wall.
The components are interchangeable, and we know this will scandalize you Ikea fans but there's no Allen keys required; everything goes together and comes apart by hand.
The system is comprised of a veritable UN of wood: ash, douglas fir, hemlock, hickory, oak and walnut all make an appearance. Sadly, there's no mention of whether this will remain a concept or something going into production.
