A cushion is a pillow or stuffed pad. The standard heraldic cushion is square or rectangular, with a tassel on each corner; if rectangular, as in the illustration, it is fesswise by Society default. Square cushions were also found lozengewise (i.e., bendwise) in period armory – more frequently, in fact, than fesswise. The cushion is found as a charge as early as c.1255, in the arms of Redman [ANA2 350]. For related charges, see bag of madder, wool-pack.
