Adam volumes 17/1-2 were not executed at Syon, but their design was published in volume II of The works in architecture of Robert and James Adam as being for Lord Bute. This is either an incorrect attribution, or the table was executed for Bute, and is now lost.

The three executed sideboard tables in the ante room make use of a modified version of Adam's design for sideboard tables for the dining room (Adam volume 17/3).

Today, as well as Adam's executed sideboard table in the ante room, there is also some nineteenth-century seat furniture from Northumberland House.
