    摘要： A resilient material shaped into a bent strand with a preferred length from 1.5 to 7 inches forms a filling element for cushions, pillows and upholstered articles. The strand may be bent so as to have a Z-shape or an S-shape or a V-shape or a C-shape along a portion of its length. The length of the strand is greater than its nominal cross-sectional thickness. A quantity of filling elements (e.g., the filling material), preferably formed from flexible, open cell polyurethane foam, is inserted or blown into a casing for a cushion, pillow or upholstered article. Following compression, the filling elements rebound substantially to their uncompressed state without clumping together or leaving pockets within the casing.
