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

application of non-standard furniture and underlined the observance of necessary standards
during the manufacture and equipment of schools.
