Abstract

A mattress has a resilient internal construction formed by a border surrounding a larger interior region. The border comprises a plurality of rows of pocketed springs each of which consists of a metal coil contained within a pocket of soft material. In the border coils of adjacent pocketed springs are linked to one another such that each pocketed spring derives strength from an adjacent pocketed spring making the border more rigid than the interior region of the mattress.
