침대 스프링 매트리스의 내구성 및 꺼짐(Dipping)특성에 미치는 영향 분석

Abstract

The right sleep environment for modern people is very important. While a person is sleeping, it relieves body and mental fatigue, replenishes energy, and strengthens mental functions and brain memory. Sound sleep means sleeping deeply, sleeping continuously and getting enough time. Bed mattress plays the most important role in environmental conditions for sound sleep. According to the survey when using bed mattress, the noise and dipping was the most abundant. The purpose of this study is to analyze the durability and dipping characteristics of spring mattresses of different kinds and to examine the factors affecting dipping. First, we reviewed the spring characteristics and internal structure of the four bed mattress types. And the durability test, the vertical load (hardness) test, the tensile strength test of the outer surface, and compression set of the internal material were performed for each type of mattress. As a result, the amount of dipping for each type was different. As the thickness of the internal material increased, the amount of dipping decreased. It was judged that the internal material plays an auxiliary role by alleviating the load and impact directly transmitted to the spring mattress. There was no difference in the tensile strength of the outer surface. And there was a slight difference in the elastic performance of the internal material of each type of spring mattress. The factors that have the greatest effect on dipping and durability will vary depending on the presence, thickness, and elastic performance of the internal material.
