This paper contains concise results of research on the subjective feeling of comfort while sitting on four different office chairs with various types of upholstered seats and its comparison with objective indicators such as pressures in relation to sex, mass, height and body mass index while sitting. The research included 69 students from the University of Zagreb, 25 of which were female and 44 male. The participants used subjective ratings to rank the chairs according to the level of comfort they provided: 1. Seat made from slabstock polyurethane foam, 2. Seat with a net, 3. Seat made from cold casted polyurethane foam and 4. Seat made from perforated cast polymer. Considering the obtained results regarding pressures and load (mass) while sitting, it can be asserted that for men the highest pressure rises depending on the increase of load on the seat. For women, the highest pressure decreases with the increase of load on the seat, while, regardless of the participant’s sex, average pressure rises with the increase of mass on the seat. Bearing in mind the results regarding pressures and height while sitting, it can be concluded that for men the highest pressure rises with the increase in height. Average pressure in accordance with men’s height increases on all four types of chairs, while for women, the pressure decreases as height increases. Considering the results on pressures and absolute BMI values while sitting, it can be asserted that for men the highest pressure rises with the increase of a person’s body mass index, while for women it decreases. |
