When you strike a ball, its speed, velocity, direction and smoothness of the roll depend on the quality of the playing surface (bed). It can make the difference between winning and losing a game. Hence, it is essential that the pool bed be absolutely flat and does not warp or otherwise deform with time. Choose a pool table with any of these playing surfaces:
Slate - the best pool bed surfaces are made from slate, a type of stone that can be finished immaculately to give a smooth, level, and dimple-free striking surface. The standard thicknesses are ¾", 1", and 1 ¼". The Billiard Congress of America (BCA) has approved 1" as the competition-grade slate thickness.
Felt - a fabric made from wool and nylon, is also an ideal surface material for pool tables because it does not warp or deform, offers a smooth rolling surface, and is very durable. Look for Teflon-coated felt for spill and stain-proof surfaces. Worsted felt is ideal because its fibers are combed before they are spun. Hence, they offer speed and accuracy to the strikes. Green and red are the most commonly used colors.
Medium-density fiberboard or MDF is used for smaller, portable pool tables. It is warp-resistant and affordable.
