• positioning a first cover positioned over the coil pack and attaching the first cover to the chassis with a first zipper at a first point of the chassis;
• positioning a comfort layer over the first cover and attaching the comfort layer to the chassis using a second zipper at a second point of the chassis;
• and
• positioning a second cover over the comfort layer and attaching the second cover to the chassis using a third zipper at a third point of the chassis, wherein the chassis accepts the zippers at the points to establish the form and mitigate the chassis, the coil pack, the first and second covers and the comfort layer from shifting.
