Way before Flor, tatami mats were the original modular floor tile. Made of fragrant dried grasses and designed to be easily replaced if one gets soiled or wears out, these traditional foor mats make you really want to take your shoes off. The surface they create is firm but cushiony, and if you like a hard bed, you'd love sleeping on tatamis. The tatami mat, which is roughly 33.5" x 70.5", is the standard for measuring real estate in Japan, a unit known as jo (as in, "that little tea room is 6-jo and 4.5-jo") and rooms are built to neatly accomodate a specific number of mats. Here in the US it's rarely the case that rectangular tatamis will neatly cover your floor, but this new square kind is a bit more flexible. At 3'x3', these can be used much the way Flor tiles are, to cover a space floor to floor (one that happens to fit multiples of 3') or to define a special area within a room. Perfect for setting off an area in a room for yoga or meditation. Available from DharmaCrafts.
