Pad for use under a covering layer

摘要

The present invention discloses a pad for use under a covering layer. The pad can include a mat with at least one off-all portion, the at least one off-all portion having a puzzle-piece shape. The mat has a bounding portion that is complementary shaped with at least part of the at least one off-all portion, and the bounding portion and the off-all portion have an interference fit therebetween. The interference fit between the bounding portion and the at least one off-all portion provides for the off-all portion to be removably attached to the mat. In addition, removal of the at least one off-all portion from the mat provides an opening for a component to be nested therewithin, while not removing the at least one off-all portion provides structural support to the covering layer that is located over the mat.
