The Triangle Stool
I’ve looked at several versions of this style of chair and finally decided to design one that I thought could be built without having to turn the rungs. The chair is assembled using square tenons on the end of hexagon rails. Each of the tenons that protrude through the legs are secured with wedges the front rail tenons meet the side tenons and both are locked in place with a mechanical fasteners and the covered with a dowel plug. The head rest is held with a wedged through tenon and the angled support braces are totally optional.
A little History… (The history is from the St Thomas Guild)
The triangle stools (or schemel or driestal in Dutch) were very popular in medieval and later times, becoming out of fashion in the 18th century. They can be found in many medieval paintings and manuscripts, e.g. the “scupstool” of Rogier van der Weyden (around 1450) in the New York Metropolitan Museum of Art. However no real medieval examples exist in musea. John Howe has written an article in Dragon 4 of the Company of St. George on medieval seating furniture, containing many different images of triangular stools. Basically these stools appeared in two types: with and without a backrest. The turned triangular stools without a backrest were found in all kinds of sizes, and serving as seating as well as side tables. The seating could be a woven reed mat, a wooden slat or a piece of leather.
