This Fiber Fill Tatami Mat combines the classical Japanese Washitsu interior design style with a contemporary innovation. Instead of the baked rice straw fill used in conventional Tatami, these mats are made with a high-density fiberboard. The result is a lightweight, hypoallergenic mat that doesn't have the traditional scent associated with classical Tatami flooring. Traditionally, Tatami mats were symbols of wealth and extravagance, only seen in the homes and temples of the higher castes. Nowadays, Tatami mats are widely available; you can find them in many Japanese homes, restaurants, temples and tea houses.
