The purpose of this paper is to report the results of intervention on the fit of seating for elderly wheelchair users who use foot propulsion. The elderly users, who lived in care facilities, were provided with improved wheelchairs for about two months while we investigated the seating posture, independent mobility, and degree of satisfaction during use. The results of the investigation are as follows: (1) Seating pressure for the subjects who used the fitted wheelchair tended to decrease. (2) Independent mobility for the subjects using the fitted wheelchair tended to decrease. On the other hand, cases where the independent mobility improved were also observed. (3) Subjects were satisfied with the comfortable seating of the improved wheelchair. However, the small-sized elderly subjects were dissatisfied with the transfer, the meal action, and the fitted seat
