Urban open spaces provide the citizens to rest and socialize as a public space. The public space, which allows people to come together without economic, social and physical barriers, should be accessible and equally comfortable for everyone. This study aims to develop a systematic design process that allows designers to design urban furnishings such as sitting, resting and waiting in public spaces in accordance with anthropometric and ergonomic criteria. The parameters determined for sitting, resting or eating-drinking vary according to the number of people, whether they are with or without a backrest, with or without armrests, with or without a table. Depending on the number of people to use, the width of the urban furniture will change. Other variables are seat height, seat width, seat depth; backrest angle, armrest height, the height and the width of the table. The parameter for standing or resting depends on the height and the number of people who will use it.
Grasshopper plugin, which allows parametric design in Rhinoceros program, was used to establish the relationship between parameters and variables. Tables prepared in Microsoft Excel were used for data entry. The three-dimensional model is not the final design product, but aims to prepare a base at the advanced design stage.
