The biggest highlight of the M90 series ergonomic office chair is its multi-directional adjustable backrest. The backrest can be raised as a whole, which can adapt to users with a height of 160cm-200cm, and the adaptive lumbar pillow can adjust the angle according to the needs of users. The polyester mesh is stretchy enough to keep the seat cushion away from flopping or collapsing for a long time. 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 concept of ergonomic design is to bring users a more comfortable sitting experience and make users sit healthier. The S-shaped polyester backrest is not only breathable and fits the physiological curve of the human waist, but also can move up and down to meet the needs of users of different heights. The split design allows the lumbar pillow to automatically fit the waist and provide excellent support. The waterfall cushion is designed to fit the body curve of the buttocks. Polyester mesh is not only breathable, but also stretchy to give customers a soft sitting experience. The 3D armrest can be adjusted front and back or up and down, and rotated left and right.
