The curvy back rest is “coopered” – which means it is a number of thick wooden pieces whose edges are mitered and then glued to create a wide curve the way coopers used to make barrels. The “racing stripe” effect comes from coopering two sapwood edges so that it looks as though the sapwood – which is white – grew straight up through the center of the tree, and not only along the outside.
