When is a bed a book?

Bed Book, 2005, by Susan Stockwell, consists of Mills and Boons books squashed into used, rusting bed frame.

Another bed book - with a ghostly imprint - is on show at the Florence Nightingale museum in London.

Stockwell's recent work includes dresses made of maps of the Scottish Highlands, and "A Chinese Dream" was in the V&A's quilts exhibition.
