Evaluation of different combinations of classroom table heights and chairs was done on the basis of
reduction in percent increase in physiological stresses (heart rate, respiration frequency and grip strength of
working hand) and subjective feelings of discomfort as perceived by selected female students of different
height categories while performing given task of writing for 30 minutes. Findings from the Table 3 revealed
that for short stature students, combination of 43.5 cms seat height of chair and 68.5 cms high table top is
least stressful to body; whereas for medium height students, 71 cms high table top with same chair is most
comfortable set and for tall students ideal combination worked out was 46 cms high seat of the chair and 73.5
cms table top.
