In order to better apply ergonomic concepts to chairs, SIHOO has spent years of in-depth research and innovation to achieve the optimal balance between chairs and people. According to medical research, different sitting postures exert different forces on the spine, and lumbar health problems also have a negative impact on sitting postures. Lumbar stress is one of the health concerns of SIHOO designers.
