A very common pattern for chairs has each front leg connected to the back by the lateral stretchers, which in turn are connected by a medial stretcher. In the William and Mary period chi (from the Greek letter chi - Χ) stretchers were common, connecting the legs diagonally, frequently with a finial where the stretchers crossed.
In traditional chair design, a common pattern involves each front leg being connected to the back via lateral supports, which are then linked by a medial support. During the William and Mary period, chi-shaped connectors became a distinctive feature, connecting the legs diagonally and often featuring a decorative element at their intersection.
