Abstract
Abstract This invention relates to sun beds. In the described embodiment the bed has an elongate base (1) which is generally flat but has a rim (2) of inverted U-form. The base (1) is covered by a dome (4). The base (1) has a frame with a plurality of vents (11), while the dome has a vent formed in a blister (9). The vents are positioned such that solar action generates convection currents which will draw air in through the base vents as hot air escapes through the dome vent.
