Abstract
A comfort layer for a bedding or seating product has slow-acting pockets characterized by the individual springs of the comfort layer being pocketed with either semi-impermeable or non-permeable fabric. Each seam joining opposed plies of fabric around each of the coil springs of the comfort layer may be segmented, allowing air to flow between the segments, thereby increasing the luxury “feel” of the comfort layer. The method of making the comfort layer includes compressing the springs and creating pockets with a welding horn and an anvil.
