Table 6: Subjective assessments for moisture, thermal comfort on chair, and level of sweating. The LS chair stood out at points T7 and T8 (back and buttocks). Recall that the LS chair was the only one with a PUR foam backrest, whereas the other chairs had mesh. For all chairs, the lowest score corresponds to the feeling of \"cold\", and the highest score was given to the feeling of \"warm\". The mean score for the back on the LS chair was 4.59, whereas for the other chairs (with mesh) it was very uniform and ranged from 3.80 to 3.93 (Table 5). The seats all had the same cover material (100% polyester) but different combinations of polyurethane (PUR) foams. The ratings ranged from \"cold\" to \"hot\", representing the full range of the 7-point scale, with the LS and MA models having the smallest range, from \"slightly cool\" to \"hot\". The average rating for the sensation of warmth on the buttocks (T8) for the LS model was 4.83, while for the others, it ranged from 4.28 (BS) to 4.55 (MA). The responses to the questions about the thermal comfort on the backrest (T13) and seat (T14) were in line with the previous analyses and the points related to these indicators. Although the ratings range around the \"medium\" of the 3-point scale, the thermal comfort of the seat is expectedly higher, with an average rating of 2.05. The highest ratings were given to the LS and RS seats (2.08), but no other seats were rated lower than 2 (medium). The thermal comfort of the backrest was rated with an average rating of 1.88, which is expected considering the design, with the highest rating given to the LS model (2.00) and the other backtests not receiving ratings lower than 1.8. Figure 4: Mean values of assessments of thermal/moisture indicators for each chair. Figure 3: Overall average value of thermal/moisture indicators for all chairs. When we look at the responses regarding the feel of body moisture on the front and back torso and the degree of sweating (Table 5), they are in the lower range of the 4-point scale. The moisture ratings on the front torso (T11) and back torso (T12) were 1.19 and 1.25, respectively, and the average rating for the level of sweating (T15) was 1.75.
