Narration of questionnaire questions were based on the validity of the content and their reliability were confirmed with Coronbach's alpha, ۸۰%.The Collecting data was analyzed based on regression test in SPSS software, version ۲۱. The Kolmogorov-Smirnov and Shapiro-Wilk tests were used in this study. According to the census of ۱۳۹۵, Ahvaz metropolis had ۱۳۰۲۵۹۱ population, it had eight municipal districts which its' four area with the extent of ۳۷۷۲ hectares was in the first place.   Results and discussion      In the descriptive finding section, the variable of age, education, gender and occupation were examined.

Among the studied variables, citizens' satisfaction had the most standard deviation (۹/۷۰), also urban furniture had more scatter compared to other variables (۷/۹۹). But furniture design, construction and equipment indexes had the lowest standard deviation (۱/۳۷) and as a result they had the least scatter. In the inferential findings of the research with using nature tools, relevant goals and hypotheses, for investigating research hypotheses used Spearman correlation coefficient, Wilcoxon Test, non-linear regression. In the main research hypotheses examined the effect of organizing urban furniture with the view of the city.
