Chemical Tatami

Chemical Tatami is a tatami where tatami flooring is made with formation product such as a polystyrene form or an insulation board.
Because it does not use straw, a mite and mold are hard to occur and are hygienic.
This is the first factor that a chemical tatami was developed.

There is a chemical tatami with a little straw, and this is called “a straw sand tatami flooring”.
Pure straw tatami flooring is tending to decrease these days that a ratio of chemical tatami becomes more than half.
