Abstract: A conference table assembly comprises a plurality of conference tables each having a top providing a writing surface for a user, and a plurality of accessory units sandwiched between adjacent tables. Each of the accessory units has a top which is the same thickness as the conference table tops and is supported flush with them. In the accessory unit top there is an opening into a trough-like housing which is divided into compartments housing electrical and electronic components. The opening is closed by a removable panel on which are mounted such components as a goose neck lamp, microphone, keyboard, control elements, indicating instruments, etc. Preferably an accessory unit is provided between two user positions so that it can serve both. Each accessory unit preferably has a leg and foot so that it is self supporting and is provided with quick-release fasteners for connecting it to the tables.
