The information provided in the questionnaire
forms also show that 49/3% of the users were dissatisfied and felt some sorts of tiredness. The
tiring condition they complained from with regard to ergonomic disposition of the furniture which
were considered included 41/9% in the knee, 24.1% in the leg 51.2% in the back, 47.8% in the
neck, and 24.6% from the high blackboard. The current results in addition to the incompatibility
of the furniture used by the students with the anthropometrical specifications and ergonomic
standards clearly showed that tired feeling and pain of the students were mainly due to the
application of non-standard furniture and underlined the observance of necessary standards
during the manufacture and equipment of schools.
