Accredited by the Hong Kong Chiropractic Association (CDAHK), with a unique three-stage spring design,
respectively supports the head, waist and legs. The springs supporting the head and legs use 2.3MM stainless steel springs,
and the main supporting parts of the spine use 2.45MM springs to strengthen the supporting force of the waist and ensure a healthy sleep.
In addition, space memory foam is placed between the mattress surfaces, which can adjust the supporting effect according to the temperature and gravity of the human body, greatly enhancing the spine protection effect.
