Nowadays, the majority of jobs in the western world involves sitting in an office chair. As a result, a comfortable and supported sitting position is essential for employees. In the literature, various objective methods (e.g. pressure measurements, measurements of posture, EMG etc.) have been used to assess sitting comfort/discomfort, but their validity remains unknown. This review therefore examines the relationship between subjective comfort/discomfort and pressure measurements while sitting in office chairs. The literature search resulted in eight papers that met all our requirements. Four studies identified a relationship between subjective comfort/discomfort and pressure distribution parameters (including correlations of up to r = 0.7 ± 0.13). However, the technique for evaluating subjective comfort/discomfort seems to play an important role on the results achieved, therefore placing their validity into question. The peak pressure on the seat pan, the pressure distribution on the backrest and the pressure pattern changes (seat pan and backrest) all appear to be reliable measures for quantifying comfort or discomfort.
如今，西方世界的大多数工作都需要坐在办公椅上。因此，舒适且有支撑的坐姿对员工来说至关重要。在文献中，已使用各种客观方法（如压力测量、姿势测量、肌电图等）来评估坐姿的舒适度/不舒适度，但其有效性仍然未知。因此，本综述探讨了坐在办公椅上时主观舒适度/不舒适度与压力测量之间的关系。文献检索得到了八篇符合我们所有要求的论文。四项研究确定了主观舒适度/不舒适度与压力分布参数之间的关系（包括高达r = 0.7 ± 0.13的相关性）。然而，评估主观舒适度/不舒适度的技术似乎对所取得的结果起着重要作用，因此其有效性受到质疑。座面的峰值压力、靠背上的压力分布以及压力模式变化（座面和靠背）似乎都是量化舒适度或不舒适度的可靠指标。
