The best time for reversing the cover of a tatami is when it is between 5 to 8 years old. If we want to reverse a tatami cover, it should be between 5 to 8 years old.

Plastic foam has become popular as a core material for tatami, because it is cheap, and light weight, and mites are not a problem. There is a type of mite in Japan that likes to live in tatami. Recently, we have learned that plastic form is bad for our health – it can add to the “sick building syndrome” – dangerous chemicals can leak out of the plastic foam, into the air.

The main reason is construction costs. Wooden floors are cheaper than tatami floors. But many people feel wooden floors are cold in winter, so special tatami that cover wooden floors are popular. Traditionally, Japanese people sit on the floor at home – not on chairs – tatami are much more comfortable than hard wooden floors.
