Ah, the thrills and spills of a day in the office!
The humble office chair on rollers was steered at speed through the streets of the Swiss town of Olten on Saturday in an international race to the finish line.
Safety helmets were worn as some chair drivers struggled to stay on board.
Competitors came from as far afield as Germany and Austria.
But homegrown talent triumphed in the “World Championship Office Chair Race,” with two Swiss men taking top honours.
They both won a travel voucher worth 500 Swiss francs.
