OFIS ÇALIŞANLARININ OTURMA KONFORUNDAN MEMNUNIYET DERECELERI VE BIR OFIS SANDALYESINDEN BEKLENTILERI

Abstract

Oturma konforu; bireyin sandalyesinin özellikleri, kullanıcının özellikleri ve sandalyede oturularak geçirilen zamanla ilişkilidir. Ofiste çalışma saatlerinin artması, yanlış işyeri ve iş ekipmanı tasarımı; çeşitli kas-iskelet sistemi rahatsızlıklarına yol açmaktadır. Bu çalışmanın amacı; katılımcıların bir ofis sandalyesinden beklentilerini belirlemek, ofis sandalyeleri ile ilgili rahatsızlıklarını araştırmak ve ofis sandalyesinden genel memnuniyeti etkileyen önemli iş ve kullanıcı özelliklerini tespit etmektir. Bu çalışma, yapısal tasarım ve tekstil tasarımı konusundaki rahatsızlık ve beklentileri göz önünde bulundurarak bir ofis sandalyesi tasarlamayı amaçlayan, devam etmekte olan bir projenin parçasıdır. Anket sonuçlarına göre, katılımcıların beklentilerini karşılaması beklenen bir ofis sandalyesi tasarlanacaktır. Rastgele seçilmiş 382 katılımcıya, kendi mevcut ofis sandalyelerinden genel memnuniyetlerini, sandalyelerinin sahip olduğu özellikleri, sandalyeleri üzerinde kullanılan tekstil malzemelerini ve bir ofis sandalyesinden beklentilerini belirlemek için bir anket uygulanmıştır. Kadınların %74,89'unun ve erkeklerin %58,05'inin ofis sandalyelerinden memnun olmadığı tespit edilmiştir. Sandalyelerinden memnun olmayan personelin %68,75'i, rahatsızlıklarının ofis sandalyelerinden kaynaklandığını düşünmekteydi. Ayrıca, ofis sandalyesinde kullanılan tekstil malzemelerinin sandalyenin rahatlığını etkilediği ve sandalyelere kaplanan tekstil malzemelerinden bazı beklentilerin olduğu tespit edilmiştir.

SEATING COMFORT SATISFACTION LEVEL OF OFFICE WORKERS AND THEIR EXPECTATIONS FROM AN OFFICE CHAIR

Abstract

Seating comfort is related with the individual’s office chair features, user features and the time that is spent sitting on an office chair. The increase of the working hours at the offices leads to a variety of musculoskeletal disorders caused by the lack of improper workplace design and business equipment. The aim of this study is to investigate the discomfort complaints about the office chairs and the expectations of participants from an office chair and to determine the significate user and task features which affect the overall satisfaction from the office chair. This study is part of a continuing project, which seeks to design an office chair considering the discomforts and expectations in terms of structural design and textile design. Based on the results of the survey, an office chair which would is prospected to satisfy the expectations of the respondents will be designed. A survey was applied to randomly selected 382 respondents to determine the overall satisfaction level of respondents from their own current office chairs, the features of current their office chairs, the textile materials used on their office chair and their expectations from an office chair. It was found out that 74.89% of women and 58.05% of men were not satisfied with their office chairs. 68.75 % of the staff, who were not satisfied with their chairs, thought that their discomforts were caused by their office chairs. Besides, the results stated that textile materials used on office chair affect the comfortability of the chair and it is also determined that there are some expectations from the textile materials which have to be covered.
