Sihoo 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. The improved 3D armrest can be moved up and down, front and back, and left and right, so that it can better meet the actual needs of users. In addition, the original design is still retained, the PU casters that do not damage the floor, the adjustable lumbar pillow and other ergonomically designed functions. Furthermore, product warranty period is three years. If there is any quality problem, please contact us. After confirming, we will change the accessory for you. We promise to provide you with zero profit product accessories within three years of the warranty period.

Easy to assemble, good lumbar support. Only criticism is that you can’t set the armrests in place, they easily slide forward and back. Otherwise, good chair.
