In general, this study investigates the comfort and safety level of the present driver’s seat by identifying and
determining parameters which influence the comfort level and safety system of the driver’s seat. Consequently a
new ergonomically designed driver’s seat was developed so as to improve the safety and comfort level. Parameters
that influence the safety and comfort level must be considered in designing the driver’s seat. The adjustability of the
driver’s seat was the most cited parameter as having the most influence on safety and comfort level. It is clear that
the respondents used the adjustability function to alter their sitting posture. The second most cited parameter is the
seat followed by parameters of backrest; cushion material, cushion width, headrest and cushion length. Based on the
results and findings of this study, a new driver’s seat design was developed with the following dimensions of the
five selected parameters; cushion width 520.00 mm, cushion length 380.00 mm, backrest width 480.00 mm,
backrest height 407.50 mm and adjustability 180.00 mm.
