The word 'cabriole' refers to legs of a piece of furniture that are shaped in two curves. The upper part is convex, whilst the lower is concave, like an “s”. The two halves bend outward and inward, creating a 'foot' to the leg. The design was used by the ancient Chinese and Greeks, but emerged in Europe in the early 18th century, especially in France, England and Holland. Lonnie Bird says that, "nothing symbolises 18th century furniture more than the cabriole leg."
