Guerrilla upholsterer, secretly making life more comfortable

Mick Sheridan is a furniture upholsterer by day, working from his studio in rural Wales.

But in his free time, he has an alter-ego - he's the Guerrilla Upholsterer. If he ever sees a public seating area that he thinks could be made more comfortable, he secretly upholsters it - from bus stop benches to bird watchers' hides.

And he wears a gorilla mask while doing it.

BBC News spent a day on his trail.
