I still cotton wool is good, some people say that traditional cotton wool is easy to have dust affecting the respiratory tract and so on, I want to say that you are using black cotton it!

The spring must be so much more elastic than cotton! Some people say Simmons after so many years of research, high-end will go through the process of design, so that the elasticity of the spring to achieve the curve you sleep on the most ergonomic
