Art lovers will be encouraged to fall asleep at a new exhibition featuring a pair of roving robotic beds.
Two visitors to t he Hayward Gallery exhibition, Carsten Holler: Decision, will be able to stay overnight at the building on London's South Bank and sleep in the specially adapted beds.
The beds, which move at slow motion travelling less than one metre (three feet) a minute, are programmed to avoid obstacles and use a system of lasers and radio beacons to get around.
The gallery's director Ralph Rugoff said: "Visitors who get to spend a night in the gallery while transported on self-navigating beds will have an intimate and utterly unique experience of Carsten Holler's mind-boggling exhibition. On awaking, they may find that the Hayward will never look the same again."
Conceptual artist Carsten Holler hit the headlines in 2006 when several people were injured on some giant spiralling slides which he installed at Tate Modern.
His new exhibition also features two 15-metre (49 ft) high slides as well as sculptures, videos and lightworks.
It runs from June 10 to September 6 and tickets for an overnight stay are £300.
