PLY is a fictional furniture company, brand and product. The chair was designed and manufactured by hand.
The chair itself is made entirely out of plywood and is to be flat-packed and assembled after purchase. The idea behind using plywood is that — once other pieces are designed— an entire set of furniture could be cut from one sheet of plywood. This would eliminate waste and also provide customers with a unified set of furniture designed to fit any modern household.
Other ephemeral items such as rulers and pencils were created so purchasers could measure out space in their homes or make any notes needed.
