The Optimum 30 is a table with a 1 1/4 in. thick top. As a consequence, the evenness and consistency of the ball rebound is unparalleled. The top is pre- treated multiple times and then coated with a special varnish to give just the right amount of gloss and the ideal frictional coefficient. The result is the truest possible bounce, even when balls are spun at the highest level.
