本研究的目的是为卧床不起的老人及残障人士研究一种特殊的防异味床垫。在广岛的机构和家庭中，对卧床不起的老人使用的床垫进行了调查。此外，还做了两个实验。一种是通过大肠杆菌进行的，大肠杆菌通常用于抗菌活性。二是对床垫的舒适度进行评价。结果如下：1)对调查结果的分析表明，66.7%的护理人员受到难闻气味的困扰。产生异味的原因主要是房间和人的因素。2)根据量化理论2对调查结果进行分析，与臭味关系最密切的项目为患者年龄、洗澡次数、护肤次数、卧室风格、卧室大小、卧床时间、褥疮形成情况。3)抗菌活性试验表明，对纤维材料进行卫生处理时，可接受抗菌活性的影响。4)以身体动作作为舒适性指标的实验结果表明，与棉质床垫相比，特种床垫的舒适性质量较差。特殊床垫有必要考虑其物理性能。
