Pure cooling

The mattress cover is integrated with SensICE advanced cooling fiber, therefore provides a pure cool feeling from the first contact and aids in the reduction of body heat. You will effortlessly fall asleep and get a quality rest!

Pressure dispersion


As sleeping on the mattress, the body weight mostly falls on our shoulders and lower hip, resulting in higher pressure on the skeleton in these positions. Compared to other mattresses on the market, OYASUMI Tancho is able to disperse the body pressure evenly, which can be seen by fewer red points and much more blue points spreading on the whole body.

  • The greater the contact area, the better the ability to support the body.
  • The smaller the average pressure, the better the ability of pressure dispersion.

With OYASUMI Tancho mattress, more body sensing area and lower average pressure provide a more uniform distribution of body pressure.
