II. Functional Feature Analysis

1. Seat Cushion Design: Filled with a combination of 3A plush cotton and sponge, it provides a medium firmness with good resilience, ensuring no pressure during long sitting.
2. Backrest Adjustment: Supports infinite adjustment from 95° to 160°, with the lumbar support height freely adjustable (e.g., within a 6 cm range), fitting the curves of the waist and neck.
3. Seat Depth Adjustment: Some models offer a 5 cm adjustment in seat cushion depth to accommodate different sitting postures.
4. Reclining Structure: Features multi-position limiters and infinite damping adjustment, ensuring coordinated linkage between the backrest and seat cushion when lying down, with the footrest extending synchronously and automatically resetting when getting up.

III. Key Selection Points

1. Backrest Fit: Prioritize models with memory foam or high-resilience sponge filling layers. Focus on testing whether the 105° - 135° range naturally fits the waist and neck, with the lumbar support floating according to body posture.
2. Seat Depth and Height Match: The standard seat depth is 40 - 48 cm, and the seat height should support placing both feet flat on the ground with the thighs at a 90° angle to the ground. The adjustment knob should be smooth, with the gas lift升降（这里原文可能有误，推测是升降平稳相关意思，英文保留原表述体现原文情况） operating steadily. The span from the lowest to the highest position is recommended to be ≥12 cm.
3. Fabric Breathability: For mesh fabrics, choose high-density weaving with elastic fiber blends. For genuine or faux leather, ensure they have microporous technology and an underlying elastic base fabric, with quick rebound when pressed and a surface temperature increase of no more than 2°C after long sitting.
4. Armrest Adaptability: The ideal state is four-way adjustable armrests with reasonably positioned adjustment knobs. When testing actions like typing or resting the chin, the armrests should lightly touch the outer sides of the forearms, with the elbows naturally bent at 90°.
