The lumbar support has three levels of intensity adjustment. By simply flicking the intensity dial, users can switch among three support sensations and easily choose the appropriate level according to their own needs for lumbar support intensity. The 6D magic armrests can be adjusted in terms of height, rotation, forward and backward movement, and folding to match different sitting postures and provide comfortable support for the arms. The headrest supports height adjustment and multi-angle rotation, allowing it to fit the neck and back of the head positions and relieve neck pressure.
