Abstract
A synthetic turf surface for golf courses, tennis courts and other grass-surfaced game playing fields is formed of a synthetic grass carpet having a flexible base sheet with closely spaced-apart upright, blade-like strands of plastic material forming a dense grass-like surface. The carpet is supported upon a cushioning underpad which is formed of a thick, molded sheet of open cell, expanded bead polypropylene. The resiliently compressible polypropylene underpad combined with the synthetic grass carpet closely simulates the feel of a natural grass covered playing field surface.
