Mattress hardness test (waist suspension/joint compression) standard

A really good mattress not only provides a comfortable sleep experience, but also an important partner in maintaining bone health and protecting joints. We understand that inappropriate hardness is a common culprit that causes tossing and turning at night and back pain in the morning. To this end, we introduce and strictly follow a set of scientific and intuitive hardness testing standards, focusing on the two core dimensions of lumbar support and joint pressure, to ensure that every mattress can be a reliable guardian of your health.

Waist Hanging Test Standard

The ideal mattress should perfectly fit the natural physiological curve of the human spine. We use a standard pressure sensing model for testing: when the tester is lying on his side, the mattress must provide sufficient support to the waist area to ensure that the spine is in a natural horizontal line. The quantitative standard is that the gap between the lower edge of the waist and the surface of the mattress should not exceed 1.5 cm. Meeting this standard can effectively support the lumbar spine and avoid muscle tension and strain caused by insufficient support.

Joint compression test standard

A hard mattress can directly compress the shoulder and hip bones, affecting blood circulation and causing pain. Our test simulates a person lying on their side, requiring the mattress to support the torso while allowing the two pressure points of the shoulders and hips to sink moderately. Based on high-precision pressure profile assessments, the peak pressure on the protruding joint must not exceed 30% of the surrounding average pressure. This ensures that the pressure is evenly distributed, providing solid support while greatly relieving joint compression.

We integrate these two core standards into every aspect from research and development, material selection to quality control. Because your health and comfort deserve our most rigorous scientific attitude to protect. Choosing our mattress is a choice of a good night's sleep and an investment in long-term bone health.
