I thought I'd post some pictures of the stools that I used for the motorbike that I made the other day. They came from Argos and are from the Habitat Tam Tam range - they come apart into three parts, two cone like bits and a plate like seat to sit on. The bonus of this is that you can fit one bit in from the bottom, one bit in from the top and then use balloon straps over the top cone and under the seat to hold the balloon bike on.
