ABSTRACT:
A chair or bed consists of a base structure forming a closed, external housing and a body-supporting means which cooperates with the housing to provide a chamber which is closed but for pressure relief openings. One or more loudspeakers is mounted in the chamber facing the body-supporting means, and each speaker is operatively connected to an amplifier so that it may produce vibrations within the chamber which are in the audible frequency range, and which are transmitted through the body-supporting means to an occupant thereof. The amplifier is of standard type which functions either with a radio receiver or with a phonograph, and which has a volume control for varying the intensity of the vibrations and tone controls for varying the output as between bass and treble.
