Abstract
A bed having a hard sleeping layer with a conduit embedded in the layer. The layer rests on a thermally insulating layer. The conduit loops across the surfaces. A steam generator directs steam through the conduit to warm the bed. The steam passes to a condensor which condenses the steam and passes the resulting water back to the steam generator. Operation of the steam generator is controlled by a thermostat. A sight gage permits observation of the level. An arrangement is provided for flushing the conduit.
