Designers mark fall of Berlin wall

Three designers have devised a novel way to mark the upcoming 20th anniversary of the fall of the Berlin wall.

When the wall came down on 9 November 1989, East Berliners were allowed to travel to the West for the first time in nearly 30 years.

The artists have created mattresses covered with slogans and quotes echoing the past.
