    Abstract: A golf swing practice mat comprising a rigid frame retaining an artificial turf mat under tension within the frame and along the upper edge of the frame. During use the artificial turf mat held under tension will support a golf ball with or without the use of a tee and will be displaced downward upon impact with a golf iron or wood in a manner such as to simulate the feel of a golf swing on a golf tee or a natural fairway. The device can be further used with selected top surface layer to simulate a divot producing golf shot from the fairway or rough as well as a golf shot out of a sand trap.
