<p>The seat consists of a rigid base with a flat horizontal section (11) and a curved section (12) with a radius of curvature reducing continuously towards the seat's front edge (10). The seat consists of a rigid base with a flat horizontal section (11) and a curved section (12) with a radius of curvature reducing continuously towards the seat's front edge (10), such that the angle formed between a tangent to the curved surface and the plane of the flat section increases from the flat section to the front edge from 0 to 50 degrees. The seat is covered with a material that is sufficiently firm so as to follow the contour of the seat, and is covered in turn by a thin layer of horse hair and cotton or tapestry.</p> |
