Abstract
People spend 33% of their life for sleeping. Sleep quality tends to affect on the efficiency of the work or study. However, the characteristics of the bed will influence the sleep quality. In order to meet the needs of users, various beds, mattresses and toppers design features are developed, such as the beds with surface design, ventilation and adjustable function. This study evaluates on the surface design of mattress toppers . Thirty two participants were recruited. The four experimental mattress toppers were tested. The study selected the toppers with 30 and 70 mm thickness. Two toppers are with surface design, two are original without design. All the material of the toppers are the same. In the experiment, the objective and subjective data the pressure distribution, temperature distribution, microclimate, EMG, spinal alignment and the comfort rating when the participants lying on the toppers were collected.The result showed that the toppers without surface design had the lower pressure distribution and the 70 mm topper without surface design induced the lower pressure than the other three toppers. The toppers with surface design had the lower temperature and relative humidity. No significant differences were found between toppers in EMG and spinal alignment measure. And the 30 mm topper without surface design had the best performance in comfort rating. The finding of the research can be used as the future guidelines for the mattresses recruit and manufacturing.
