What is a waterfall seat edge on a drafting chair?

A waterfall seat edge is a design feature where the front edge of the seat cushion curves gently downward rather than ending in a sharp horizontal edge. This curve reduces pressure on the back of the thighs and improves blood circulation in the lower legs — particularly important for users whose feet are off the floor (as is often the case with drafting chairs). Waterfall seat edges are an ergonomic feature worth looking for, especially for users who sit for extended periods. Compare it to a standard flat-edge seat by sitting in both and checking whether you feel pressure at the front edge of the seat.
