Bed warmer

This flat, round, nickel-plated bed warmer has a stem and black handle. The bedding is warmed via conduction through the walls and convection through the holes in the lid. The device is the electric version of the antique copper bed warmers that used hot stones or glowing embers as their heat source. An electric lead goes through the handle and the stem to the 30 watt heating element in the appliance.
