from a line drawing to a stool

My very first prototype build. Some criteria: max height 550mm, holding a min of 60kg weight and shouldn’t weigh more than 1.5kg. Things to consider: folding, packing, stacking and carrying. 

My concept involves two main ideas: it is made up of two simple shapes that interact to make an inquisitive and playful extra seating option. One element acts as a handle or arm, and the other as the seat. It can be flat packed and easily assembled by a single person. Similarly, it can be disassembled and stored away easily or hung on the wall as an interesting talking piece.
