When they were first made, Tatami mats were seen as luxury items for the wealthy when most people had dirt floors. Another function of Tatami was to indicate rank. The most exalted members of a ceremony or gathering were given the privilege of sitting on the Tatami, while others sat on the wooden floor. Tatami mats are much more widely used today, but are still employed for Japanese religious rites and tea ceremonies.
These Tatami mats can be used in a variety of ways. Floor coverings are the most popular option, but benches, stools, tables and desks can also be constructed using multiple Tatami. These Tatami mats are constructed of Japanese Rush Grass with a double layer top for extra protection. The inside is a baked Dried Rice Straw Fill for strength and durability. Each mat is sewn with a black fabric border and bound with twine. A moisture resistant barrier is included in the foundation of the mat.
