Body pressure distribution research and zone design of pocket spring mattresses

With the increased demands on sleeping quality, the zoned pocket spring mattress (PSM) designed and manufactured using ergonomic principles is getting popular. This study investigated the pressure distribution of buttocks and shoulder zones of pocket spring mattresses using a body pressure distribution measure system. Test results indicated that pocket spring type and cushioning material type, and people sleeping positions had the influences on body pressure distribution. A soft PSM had a lowest peak pressure in the buttocks zone, and a medium elastic PSM had a lowest peak pressure in the shoulder zone. Based on the experimental results, an optimal design scheme for zoned pocket spring mattresses was proposed.
