What is a waterfall seat edge and why does it help?

A waterfall seat edge curves gently downward at the front of the cushion — typically 15–25 degrees — which takes pressure off the soft tissue behind the knees and along the underside of the thighs. A flat, hard front edge can cut into that area for users whose feet don't fully reach the floor, which restricts circulation over time. Waterfall edges are standard on most mid-range and premium commercial chairs. FindOfficeFurniture.com notes seat edge design in product specs — call 888-719-4960.
