Additionally, the adjustable armrests allow users to modify the height and angle according to their arm support needs, further enhancing the user experience.

2. MARKUS Marcus (IKEA) The MARKUS Marcus office chair focuses on manual adjustment as its key selling point, with a design that emphasizes dynamic support and comfort. The main adjustment features include:

• Tilt tension adjustment: Users can control the resistance of the backrest via a manual knob, adapting to different body weights or sitting habits to ensure stability during tilting;
• Seat height adjustment: Manual elevation and lowering are achieved through a gas lift, accommodating users of different heights;

3. Some Low-Priced Office Chairs Market research indicates that some office chairs priced between 111.6 yuan and 354 yuan also feature manual adjustment capabilities. Although their configurations are relatively basic, they meet fundamental needs. Common adjustment features include:

• Headrest adjustment: Manual adjustment of height or angle to support the neck;
• Lumbar support adjustment: Manual modification of the lumbar support position through elastic or mechanical structures to alleviate lower back pressure;
