Influence of Sleeping Posture on Zoned Mattress for Wood-based Furniture

Abstract

Zoned mattresses for wood-based furniture have been influenced by the sleeping posture of the human body. Due to the different weights of various parts of the human body, lying on the mattress for wood-based furniture with uniform elasticity for a long time can cause illness. Therefore, dividing the mattress into different zones provides an effective solution for improving sleep quality. Herein, this work examined the impact of division size on a five-zone mattress on subject posture in various sleeping positions. Compared with conventional wood-based furniture structures, which often lack flexibility in localized support, the zoned mattress demonstrated superior adaptability in accommodating body contours. The results of the subsidence test suggested that the elastic distribution of the selected mattress was appropriate. The spinal positioning point indicated minimal impact of the size of the zone on the spinal curve of a supine position. Furthermore, the results of the body pressure distribution test revealed a significant influence of the zoning dimensions of the zone on the overall maximum pressure exerted on the human body, reaching up to 12.2 KPa. These findings offer valuable theoretical insights into designing zoned mattresses for wood-based furniture that accommodate human sleep posture.
