It is a zabuton designed for a gift in celebration of someone’s longevity.
There are some other zabutons designed for the same purpose such as a ‘kanrekizabuton’, ‘koki-zabuton’, ‘kiju-zabuton’, ‘sanju-zabuton’, or ‘beiju-zabuton.’
Those zabutons are really comfortable to sit on because of its thicker cotton batting. For more details about those zabutons, please see the description of each zabuton.
