Swivel chair

A concept of a rotating chair with swivel castors was illustrated by the Nuremberg noble Martin Löffelholz von Kolberg in his 1505 technological illuminated manuscript, the so-called Codex Löffelholz, on folio 10r.

[1] It is purported that Thomas Jefferson drafted the United States Declaration of Independence in 1776 while sitting on a swivel chair of his own design.

[3] An earlier prototype of a swivel chair dates back to a 1505 illustrated manuscript from a German noble named Martin Löffelholz von Kolberg.

[5][2][6][7][8] Jefferson heavily modified the Windsor chair and incorporated top and bottom parts connected by a central iron spindle, enabling the top half, known as the seat, to swivel on casters of the type used in rope-hung windows.

[9] Jefferson later had the swivel chair sent to his Virginia plantation, Monticello, where he built a "writing paddle" onto its side in August 1791.
