Description

Breathable foam structure and breathable pillow

This creation relates to a foam structure, in particular to a breathable foam structure and a breathable pillow.

Pillows or cushions commonly used in the market are usually made of cotton, sponge or foam. The structure is integrally formed, and the surface is processed into a curved surface to conform to ergonomics. When lying or sitting, the human body and the contact form a cushion to achieve comfort sex and support.

However, the above-mentioned structure, because the overall pillow structure is integrally formed, when the human body lies on the pillow and squeezes the inner space of the pillow, at this time, because most of the pillows are made of soft materials such as foam, cotton or sponge, they will be flattened. And become tighter, although it can provide a certain supporting force, but after a long time of use, the heat energy of the human body will be transferred to the inside of the pillow, causing more and more heat to accumulate inside the pillow, and the inside has become very tight due to extrusion. The phenomenon of being unable to breathe freely causes the heat to be accumulated in the pillow, which will cause uncomfortable feeling after long-term use, and the pillow will become inelastic and deformed due to long-term extrusion; the one-piece structure is thick but also As a result, the ventilation is not good, and it will feel stuffy after a long time of use, and the overall feeling is bulky because of its thickness.

The purpose of this creation is to provide a breathable foam structure and breathable pillow, which can provide breathable and elastic support.
