The White House bought a set of diminutive, cane-back mahogany armchairs from Davenport &amp; Co. in 1902. Nearly-identical chairs, but with leather backs, had been made by the company for the Massachusetts State House. President Hoover installed six of the cane-back chairs his rebuilt Oval Office in 1930. President Franklin D. Roosevelt moved them into the modern Oval Office, completed 1934, where they have been used by every president since. The chairs are currently in use in the Oval Office, including a pair flanking the Resolute Desk.
