The purpose of this study was to determine if ratings of discomfort differ over time between two ergonomic chairs of the same approximate cost. Twenty participants from a metropolitan university sat on two types of ergonomic chairs for 1 hour and 30 minutes while performing typing, reading, and writing activities. Repeated measure three-way and two-way analyses of variance were used to uncover the effects of the ergonomic chair design on discomfort. The data were collected using the General Comfort Rating Scale and the Body Part Discomfort Rating Scale, which were administered at 0, 30, 60, and 90 minute marks of each session. The results revealed: (1) discomfort increased over time, (2) no significant difference was uncovered between the two chairs, (3) most discomfort was reported in the lower back, (4) number of body parts with discomfort was reduced when chairs were varied, and (5) discomfort was influenced by the activities performed.Subjects--Topical Terms:
