Abstract
A cushioning and positioning pad has a body formed from superposed layers of resiliently compressible foam material and a reinforcing sheet embedded between adjacent layers. The reinforcing sheet is of such stiffness as to resist contraction along its length and width dimensions, but is resiliently bendable in response to the application of a force along its thickness dimension. The reinforcing sheet resists undesirable contraction lengthwise and widthwise of the pad when the latter is encapsulated in a curable coating of material which shrinks as it cures.
