Webberley Antiques has dated this piece to the Georgian era.

Lovely shape to the back legs which kick out at the floor. The outswept arms on curved supports terminating in fluidly carved scrolls.
A very substantial and heavy chair, the deep seat rail over squared legs to front and rear with beautifully chamfered inner faces and original glue blocks (with V shape clamp points and evidence of original makers batons) co-joined by an offset box stretcher - all in the manner of Thomas Chippendale.
The drop seat pad newly upholstered in a top quality white silk and navy cut velvet fabric in an 18th century design.

Comfortable and spacious, solid with no weakness and entirely suitable for use. A particularly good example in the finest quality mahogany made by a highly skilled hand in c. 1765.

20 inches from floor to top of seat rail
