ABSTRACT OF THE DISCLOSURE A preform is made by casting a copolyester polymer elastomer into a block. While the block is solidifying, pressure is supplied to the central portion thereof. After a block is formed, it is annealed and a precompression force is applied thereto sufficient to compress the block to an extent greater than thirty percent of the original dimension of the block as measured parallel to the precompression force. In one embodiment a cushioning unit using the block is made by placing a pair of multi-apertured metal plates on opposite sides of the block with projections on the plates extending against the block and applying a second precompression force to the block and plates sufficient to cause the copolyester polymer elastomer to flow into the apertures in the plates and form a mechanical bond between the block and the plates.
