A rich and inviting addition to any room or space, these Tatami Goza Mats are made from Japanese hand-woven rush grass. This mat looks very much like the top layer of a tatami mat and is very lightweight and portable. It can be rolled up easily and works well in an informal room like an entryway or for outdoor yoga or a day at the beach. The 3'x6'x 1/6" (90 x 180 cm) mats have a cotton border in your choice of black or a black brocade border. The goza mat is also available in a 3'x 6.5'x 1/6" length. They have no backing as they are made of rush grass so a non-skid rug liner is recommended for indoor use.
