Pad structure

Abstract

A pad structure contains a pad unit having a lateral gap formed along a peripheral side thereof. The pad unit has a first pad body and a second pad body which are at least partially spaced apart from each other by the lateral gap. The pad unit is used as a pillow and has two pad bodies for increasing support capability. In addition, the lateral gap between the two pad bodies can absorb a part of deformation. In other words, the two pad bodies flexibly expend and retract in the lateral gap so as to prevent the pad unit from depression and deformation and to well support a user's head.
