Rush tatami has various features and advantages.
Traditional Japanese traditional Rush tatami mats use rice straw for the tatami floor and woven Rush on the tatami mat surface, that is, the main material is plant fiber. Therefore, it has elasticity containing moderate air.
Even for Rush tatami mats that do not use modern rice straw or rush, this characteristic of elasticity has been inherited because materials that are similar in usability to traditional materials have been selected.
The tatami mat is also characterized by its excellent heat insulation and moisture retention due to its airy finish. In particular, Rush tatami mats made from traditional rice straw have excellent moisture absorption and desorption.
When rice straw is used for tatami floors, the traditional material Rush tatami is also flame-retardant because it is strongly compressed and hardened.
