A golf mat contains a base mat, a spherical driving mat having a synthetic turf at the top, a spherical recess with a synthetic turf at the base and is affixed in a spherical alcove of the base mat by pin and a supporting plate whose diameter is similar to that of the driving mat. It is installed beneath the driving mat. Every time a ball hit off against the driving mat, this makes the driving mat to rotate so as to use the whole area of the driving mat evenly. Certain golf mats that are marketed have a driving surface of a spherical shape so that driving region can be revolved when the ball is stroked. The location of the ball when stroked is likely to be placed in the innermost region of the mat. Usually golf mat utilizes synthetic turf which is placed on an orthogonal base plate. The driving mat is replaceable and is very economical.
