University students are being offered the chance to catch up on sleep between lectures in a "napping centre".
The University of East Anglia's (UEA) student union said its "nap nook" was the UK's first such facility in a university setting.
The idea is based on a facility at a US university, designed by a student there and run by its psychology department.
UEA students in Norwich are able to book a 40-minute "nap nook" slot in advance or walk in on the day.
The specially-fitted out room contains bean bags, sofa beds, anti-microbial pillows, eye masks and blackout curtains.
The room, which is open from noon to 18:00 each day, is monitored by CCTV.
