I’m Anthony, my hometown was in Fo Shan, because my parents were not well educated and know nothing about the negative consequence that a bad mattress will bring. As a result, a low-quality spring mattress slept with me for more than ten years. After a period of time, the centre of the spring mattress sags and loses the support to my backbone during sleep. Along with the pain gain by difference sports and lack of relaxing during sleep, back and waist pain became one of my ‘best’ friends.
