With regard to the design of desks and chairs for schools or offices, there are great variations in the physiques of the users. Of various specifications for desks and chairs, height is a crucial dimension that can affect the comfort and convenience during usage. Compared to providing a series of desks and chairs with different heights for the user to choose, adjustable desks and chairs take into account both manufacturing costs and the scope of usage, and constitute a more suitable solution. This paper integrates principles of human-factors, engineering, and anthropometry to propose a height adjustable concept model, the User/Effect/Product model. This model explains how to shift from a product that emphasizes function to design thinking that focuses on how users will use the product. Finally, this model was applied to propose several design case studies to prove the applicability of the User/Effect/Product model.
