Performance of pocket spring directly influences body pressure distribution characteristic andhuman comfort of mattress. By using spring tension and compression testing machine and body pressuredistribution measure system, the paper measured elasticity of pocket spring and body pressure distribution ofpocket spring mattress, and analyzed the influence of the soft hardness on the body pressure distribution ofthe pocket spring mattress. The results showed that elastic modulus of pocket spring is closely related to itsline diameter, intermediate diameter and cylinder number, the selection of pocket spring is very important fordesign of pocket spring mattress. For pocket spring mattress, maximum pressure and maximum pressuregradient on the “medium” pocket spring mattress are the minimum, comfortable sensation is the strongest.
