2. Aroma Effect
There is an aroma effect on the "Tatami" mats. According to the several studies that the fragrance of the rush stabilizes mind
3. Cool Summer & Warm Winter
It is very humid in Japanese summer. Homes designed with "Tatami" mats can help to create a natural, less humid, and airly environment. The air trapped inside "Tatami" mats works as a natural insulator, slowing the movement of heat within the building and keeping the room cool. On the other hand, they are also suitable for the cold dry winter as the air in the mats prevents heat from escaping and evapolates humids in the air
4. Sounds Insulation
"Tatami" mats not oly insulate the air, it also insulates sounds. It prevents echoing of footsteps and also living sounds such as TV and musics
