===Cushions===
Cushions (also sometimes called "rail cushions", "cushion rubber", or rarely "bumpers") are located on the inner sides of a table's wooden {{Cuegloss|Rail|rails}}. There are several different materials and design philosophies associated with cushion rubber. These cushions are made from an elastic material such as [[vulcanized]] [[rubber]] (gum or synthetic). The purpose of the cushion rubber is to cause the [[billiard balls]] to rebound off the rubber while minimizing the loss of [[kinetic energy]].{{citation needed|date=October 2022}}

The ''profile'' of the rail cushion, which is the cushion's angle in relation to the bed of the table, varies between table types. The standard on American pool tables is the K-66 profile, which as defined by the [[Billiard Congress of America]] (BCA) has a base of {{convert|1+3/16|in}} and a nose height of {{convert|1|in}}.<ref name="BCA Equip.

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.<ref name="BCA Equip. Spec." />

Snooker tables use an L-shaped profile, such as the L77 profile.{{citation needed|date=October 2022}}
