A survey was conducted on 100 students who took part in the previous tabloid chair design and have used the tabloid chair that was designed earlier for at least one hour at a time. This survey mainly focuses on the discomfort of the users. The results show that 14, 16 & 23 of the users felt discomfort at their neck, lower back & shoulder respectively. A new design was proposed for tabloid chair, by analyzing the survey results and using anthropometric data taken from 150 students who took part in the previous study. So the users may not face further problems. Taking cost of materials and other factors into consideration a tabloid chair was fabricated using ergonomics design concepts. Then, a comparison was done between the fabricated tabloid chair and the existing tabloid chair, which is shown in the final chapter.
