Details of the Chairs of Estate from the announcement of historic chairs reused for the coronation:

Her Majesty Queen Elizabeth II used her Chair of Estate during the 1953 service, while the companion Chair of Estate for Prince Philip, The Duke of Edinburgh, was not used at the Service itself but was delivered to Buckingham Palace, where both Chairs have been on display in the Throne Room for many years.  The Chairs of Estate are made from carved and gilded beechwood in the seventeenth century-style which was used for earlier Chairs of Estate. The cyphers of Queen Elizabeth II and Prince Philip are featured in the carving of the giltwood stretcher joining the front legs, together with the national emblems of a rose, thistle, and shamrock.The Chairs of Estate will be used during the early parts of the Service and for the Coronation of Her Majesty The Queen Consort.

In preparation for the Coronation, Gilding and Furniture Conservators from the Royal Collection Trust have cleaned, restored and consolidated the giltwood frames. New silk damask was woven by the Humphries Weaving Company, Suffolk to the same pattern with which they were originally upholstered. This was to allow for the cyphers of The King and The Queen Consort to replace those of Queen Elizabeth II and Prince Philip, which were removed and will be kept in the Royal Collection. The new cyphers for the Chairs of Estate have been hand embroidered by the Royal School of Needlework, and created with cloth of gold, woven with a metal thread. The cloth of gold was then embellished with gold metallic threads. Upon completion, the cyphers were applied onto the silk damask using the appliquè technique. The upholstery was completed by the Royal Household’s upholsterers, including the re-use of the original braid and trimmings.
