A classic example of Cotswolds School furniture, it drew a decent competition that carried it above the £6000-8000 estimate before it was knocked down at £33,000.
The piece was owned first by the Gimson family of furniture makers and had remained with their descendants until the 1980s.
It was subsequently given to Sir Anthony Denny, who lived at Daneway House in the late 20th century, before ending up furnishing Priests House, a National Trust-owned property in Muchelney, Somerset.
Measuring 7ft 2in (2.18m wide), the back of the settee had vertical chamfered splats and a carved chevron design. Barnsley and Gimson both used chamfering on their furniture, apparently inspired by the structure of farm wagons.
The sale at Lawrences on October 12 follows the auction of five pieces of Sidney Barnsley furniture at Woolley & Wallis in June 2016. Consigned by direct descendants of the craftsman himself, they sold for a combined £33,800.
