This thesis claims that ergonomics and function plays the most important role in the design of health equipments. Every detail is designed according to both ergonomic values of human anthropometry and object's function, of which are the major parts of individual expectations from the object.As a designed object after a case study, the general purpose hospital bed is a product derived from the dimensional limitations of human body. In the design progress, the spine, pressure points in laying position, have been analised, the functions that a general purpose hospital bed should bring, have been discussed. Also the target market, customer and user differences, are examined.This analysis have led to a conclusion of a hospital bed as a designed product for a target customer.Keywords: Ergonomics, Human-machine Interface, Bed, General Purpose Hospital Bed, Spine, Back, Pressure Points, Matress, Function.
