Abstract
The subject matter is a cushion core construction in which individual elements of cushion material in plug-like form are connected together in a string by capturing them between two strips of flexible sheet material which are joined together between adjacent elements to hold the elements in place. The preferred structural unit is a two-row module formed by joining two such strings at intervals of at least two elements to enable them to stand alone, and to facilitate their handling in their assembly with like modules to form a more extensive core.
