An audio communications system for an office chair provides a user with private listening of RF transmitted audio messages in an exposed environment such as an office area, without the use of headphones. An audio module, which mounts to the backrest of an office chair, includes an RF receiver and a shaped, acoustic horn loudspeaker which directs sound upwardly, behind the user\s head, while minimizing lateral dispersion of the sound. In another aspect of the invention, the audio communications system includes a transceiver for two-way communication, such as telephone, and an armrest mounted microphone and keypad.
