The ready room desk appears in Picard’s ready-room on the Enterprise-E in Star Trek: First Contact. Picard has a new desk by the time Nemesis rolls around, but this was his desk for a time (although his had reddish colouring).
The “coffee table” appears in Janeway’s ready room, in front of her couch.
The glass-topped dining table appears in various ship’s quarters.
The triangular stool appears in the background of sets such as the Voyager sickbay and medical lab.
