A large number of studies show that the ergonomic design of the mattress has a direct relationship with human body dimensions, such as height, weight, spine curvature and so on. And human spine curvature is an important influence factor for the ergonomic design of mattress. This study aims at establishing the ergonomic design index of mattress and obtains the human body dimensions used for ergonomic design of mattress. Based on the collected human body data, the contrastive analysis on the spine curvature of different groups of people was conducted.
