This chair has generous and elegant proportions typical of the chairs made from 1770 onwards and includes the use of the curved underarm support rather than the turned support which had become fashionable by the 1830's. However, the use of the raised three ring turning on the legs indicate that this chair was made between 1835-1870, when this particular turning was most commonly used. See Dr. B. Cotton The English Regional Chair, Woodbridge, 1991, p.51 for a dating chronology of Thames Valley Windsor chairs based on their leg turning devices.
