I designed the slatted stool in my first year at the Royal College in 1983. The original model had rather narrow seat slats and people mistook it for a towel rack! It was also so far as I remember the first design of mine to be produced in significant numbers. I modified the design for SCP, making the slats wider, but on the current production model they are narrower again. It was a simple structural exercise to bend a single length of tube and to brace it where necessary to provide a seat.
