Pillow with composite material supporting structure

Abstract

A pillow has a supporting structure and a cushion. The supporting structure is made of composite materials and is pre-stressed and resiliently bended. The cushion is resilient and covers the supporting structure. With the supporting structure and the cushion, the pillow provides two-stage resilient support. When a user rests his head on the pillow, the cushion is compressed easily at first, and then the supporting structure being resiliently bended provides sufficient support to the cervical spine of the user, making the cervical spine of the user rest in natural relaxation when the user rests on the pillow.
