The aim of this study was to determine optimum seat depth using subjective assessments. Comfort and discomfort evaluation, as an ergonomic subjective method, was used to find the optimum seat depth. A total of 36 university students rated the comfort and discomfort of six different seat depths (including 32.0, 37.0, 42.0, 47.0 and 52.0 cm which covered the buttock-popliteal length [BPL] range as well as 40.2 cm representing the 5th percentile of the BPL) during a 90-min period using a chair evaluation checklist. The results showed that a seat depth of 40.2 cm (equivalent to the 5th percentile of the BPL) was more comfortable and caused less discomfort ratings after 90 min compared to other experimental seat depths. The findings suggest that an appropriate seat depth for the studied population can be recommended based on the 5th percentile of the BPL as an anthropometric criterion.
本研究旨在通过主观评估来确定最佳座椅深度。舒适度和不舒适度评估作为一种人体工程学的主观方法，被用于寻找最佳座椅深度。共有 36 名大学生在 90 分钟内使用椅子评估清单对六种不同座椅深度（包括 32.0、37.0、42.0、47.0 和 52.0cm，涵盖臀-膕长度 [BPL] 范围，以及代表 BPL 第 5 百分位数的 40.2cm）的舒适度和不舒适度进行了评价。结果表明，与其他实验座椅深度相比，40.2cm（相当于 BPL 的第 5 百分位数）的座椅深度在 90 分钟后更舒适，不舒适度评分更低。研究结果表明，可以根据 BPL 的第 5 百分位数作为人体测量学标准，为研究人群推荐合适的座椅深度。
