Billiard table
Cushions
On a carom table, the K-55 profile is used (with a somewhat sharper angle than pool cushions). K-55 cushions have cloth, usually canvas, vulcanized into the top of the rubber to adjust rebound accuracy and speed.
Bed
For tournament competition under WPA world-standardized rules (and league play under derived rulesets), the bed of the pocket billiard table must be made of slate no less than 1 inch (2.54 cm) thick. The flatness of the table must be divergent by no greater than 0.02 inches (0.51 mm) lengthwise and 0.01 inches (0.25 mm) across the width.
