Tatami flooring refers to the traditional Japanese wooden flooring that is used in rooms such as living rooms and bedrooms. The layout typically involves a grid of tatami mats, which are square in shape and made of rice straw. These mats are arranged to form a cozy and warm space. A 'tatami flooring layout' would involve a plan or design of how these mats are arranged in a room to optimize space and aesthetics. The design may vary based on the room size, furniture placement, and cultural preferences.
