Claim:
A warp knitted elastic fabric for a cushioning surface of a body support characterized by the following elements: a base knitted fabric warp knitted from main stitch yarns; main elastic yarns, of which single fiber fineness is 1000 to approximately 4000 dtex and of which stress at 10% elongation is more than 0.1 cN/dtex, knitted in the base knitted fabric in continuous line in a selected one of the knitting width direction and the knitting length direction; main inserted yarns knitted in the base knitted fabric in continuous line in a selected one of the knitting width direction and the knitting length direction; said main inserted yarns being more bulky than both said main elastic yarns and main stitch yarns, and said main inserted yarns being visually apparently thicker as an observed value of the thickness of the yarn than both said main elastic yarns and said main stitch yarns; and the surface of the main inserted yarns being composed of multiple fibers, the total fineness of the main stitch yarn being less than one half of the total fineness of the main elastic yarn.
