The flat square cushions known as zabuton might appear at first sight to be placed haphazardly on the straw mats of the traditional Japanese room. Each is, however, positioned according to etiquette, with the pattern facing the front, for example, in order to receive the guests in the most welcoming manner. It is considered rude to move them around at will or tread on them. When kneeling on a cushion, you should place your knees onto it gently one at a time and face to the front.
