Here is a detailed introduction to several office chair backrests (single-back chairs):

• Headrest Design: The headrest has a height adjustment function, using an up-and-down bidirectional adjustment method. The resistance during adjustment is moderate, and there will be no situation where it falls off as soon as one leans on it. The pillow surface can be pushed forward, and after reaching the end, a push can make it adjust backward, with a sufficiently large angle rotation range. However, its height adjustment range has certain limitations. At its highest, the center of the pillow surface is about 67 or 68 centimeters from the seat cushion, which may not meet the head support needs of taller people. In addition, the curvature of the headrest is slightly small, and to get a good experience during support, the neck needs to be placed in the middle position.
• Backrest and Lumbar Support: It adopts a single-back chair design, with a plastic lumbar support at the back of the backrest. The height of the lumbar support is adjustable, with an adjustment range of about five to six centimeters, and there is also a knob for adjustment. However, due to the limitation of the backrest's integrity, the lumbar support cannot be pushed forward too far, and the sense of lumbar support is not particularly strong.

• Headrest Features: The headrest has a 3D design with multiple adjustment functions. It can be adjusted up and down, the pillow surface can rotate at a relatively large angle, and it also has a forward-and-backward adjustment function. Although the travel distance is not large, it can be finely adjusted in five positions, and the shifting process is smooth, meeting the needs of different users for the headrest position.
• Backrest and Armrests: The backrest is a single-back chair with good integrity. There is a hidden lumbar support at the back, which can be placed at the lowest position. The armrests adopt a 4D design, which can move forward and backward, left and right, and rotate. The support surface is relatively large, providing relatively comfortable support for the arms.

• Support System: It is equipped with an S-Flex dynamic spinal pressure distribution adaptation system. This system provides zoned support according to the physiological curve of the spine, dispersing the pressure originally piled on the waist to the head and neck, shoulders and back, back, lumbar spine, and sacrum, reducing the pressure on the waist.
• Support Structure: It adopts a FullSup full-back support structure, using a large curved surface to cover from the shoulders and back, middle back all the way to the lumbar back. Its elastic structure can be adjusted according to the force, allowing the back to always fit the backrest and providing comprehensive support.
