The M57 ergonomic office chair is an improved version of the M18 ergonomic office chair. The biggest change of the M57 is that the seat cushion uses a PE polyester mesh, so it is not only soft but also very breathable. The design of the waterfall cushion and the sponge in front of the cushion can effectively relieve the pressure on the thigh and reduce the pain in the thigh.
