The President's office chair is a Resolute Desk Chair, which was made from the timbers of HMS Resolute. The desk and chair are located in the Oval Office of the White House. The chair has a leather seat and back, and rests on four turned legs with casters.
The Resolute Desk Chair is one of several gifts that were given to President Rutherford B. Hayes by Queen Victoria in 1880. It was originally meant for use by Captain Richard Coote Roberts, who commanded HMS Resolute during its search for Sir John Franklin's lost expedition in 1852-1854. However, when the ship was returned to England, it was decided that the desk and chair should be presented to President Hayes as a token of appreciation for his efforts to secure the ship's return.
Since then, the Resolute Desk Chair has been used by every president except Jimmy Carter and Donald Trump. President Carter preferred to use a plain wooden desk that he had brought with him from Georgia, while President Trump has opted for a more modern "boardroom" style desk.
