Toileting behavior of the elderly has been a very prominent issue, because there are more obstacles and demand in this process. The elderly are the most people who use the closestool chair, but there is hardly any toileting behavior research and design for the elderly.

Thirdly, combined with the older human dimensions, analysed every size problem of closestool chair with ergonomics. At the same time, analysed the problems of structure, material, color and additional features, proposed the solutions or optimization programs. So can provide a reference for the subsequent design, and strive to design a closestool chair what is more applicable, more comfortable or more convenient for elderly people.
