Tatami or tatamis are woven straw mats, used in Japanese homes, generally as floor coverings.
these are rectangular in shape
Traditionally, rush grass was woven around a rice straw core to keep the tatami mat firm. However, now the rice straw core is often replaced with more modern materials, such as wood chips or polystyrene foam.
In shinden and shoin domestic architecture, tatami completely cover the floor.
From primitive times, the floor has remained the common surface for sitting and sleeping in Japanese architecture.
The mats work well with the unique climate of Japan, which is hot and humid in the summer and cold and dry in the winter, and the tatami mats evidently help regulate interior humidity.
