a low bed, so called from the trundles, or casters, that were attached to the feet so that it could be pushed under the master bed when it was not in use. The bed was intended for servants, who used to sleep in their employer's room so as to be near at hand. The framework was generally of oak, and suspension was provided by leather or canvas straps looped through holes in the sides.
