Abstract

A wire coil for use in an innerspring enables improved support and reduced distortion during compression. The coil comprises: a plurality of helical turns that form a helical coil body about a longitudinal axis of the coil, and which helical turns define a helical turn radius; a first coil end extending from one end of the helical coil body; and a second coil end extending from an opposite end of the helical coil body; wherein at least one of the first coil end and the second coil end include one or more touch points defined by both a first portion extending a distance from the longitudinal axis of the coil that is greater than the helical turn radius, and a second portion extending a distance from the longitudinal axis of the coil that is less than the helical turn radius.
