This the Lord Chancellor's Woolsack lies in front of the throne, and is occupied during sittings of the House by the Lord Chancellor, who is Speaker of the House of Lords. The tradition of using a 'sack' stuffed with wool is thought to date back to the reign of Edward III. In front of the Lord Chancellor's Woolsack are two other such, where High Court Judges sit at the opening of Parliament, and in front of them is the Desk of the Clerks of the House of Lords.
