Chairs have been present in many of my recent solo clown performances. Some years ago I bought some old bentwood pub chairs and took them apart. My idea was to re-assemble a chair and be able to make it fall apart at will, whilst sitting on it playing the accordion. That level of control proved impossible to achieve. Or, if it was possible, it would have taken a long time of practice, that I wasn't motivated to get into. 

Then, one day, a friend who was curating a night of improvisation performance at Chisenhale in London invited me to perform. I said yes, without thinking about it. I then had the idea to take one of my collapsing chairs with me, and to spend the 10 minutes allotted to me 'being with the chair'.
