Why the blue plastic stool beat every chair Bangkok ever imported.
It costs 80 baht, stacks twelve high, survives a monsoon, and outlived three governments — a short defence of the cheapest piece of furniture in Southeast Asia.
I bought my first one in the wet season of 1998, from a hardware uncle on Charoen Krung who wouldn't bargain past seventy-five baht because, he said, the rain was coming and he had no time. I remember watching him stack two dozen of them onto the back of a motorbike — eight on each side, eight on top — without a single strap. Twelve years later that stool is still under my mother's kitchen table, scarred from a charcoal grill she dragged across it in 2003 and never quite forgave herself for.

Soi Sakhon Plastics began injection-moulding the now-iconic short blue stool sometime around 1987, in a single piece of polypropylene with three vent slots in the seat. Within five years every som tam vendor from Hat Yai to Chiang Rai had a stack of them. The reason, according to a 2007 interview with their plant manager, was unromantic — the mould was cheap, the stackability saved cart space, and the colour was whatever pigment was on offer the week of the production run.
