These tables were executed by Sefferin Alken, in accordance with Adam's design, in 1768. They were designed to support scagliola slabs, and were sold with their slabs at Christies, London, in 1986 (now in a private collection). Harris has suggested that the tables originally stood to either side of the door from the great room into the ante room as they are too wide for the window piers.

Harris describes this design for a table frame as a 'transitional type', between Adam's heavier furniture legs, and his later, more slender designs of the 1770s. Harris also notes that this is the period in which Adam first started to use ornamental urns on the stretchers of his furniture.

Adam charged Lord Coventry £3.3s. for a table frame design made in February 1765, and £1.1s. for another in November 1768. Neither of these dates tallies with this drawing, although it is the executed version.
