Office Chair with Widening Design and Electric Adjustment

The following office chairs feature a widening design and support electric adjustment functions, allowing you to choose according to your needs:

1. Woshi Ultra Smart Control Dynamic Ergonomic Chair

Widening Design: Equipped with a 360mm integrated enlarged aluminum alloy chair base, the chair's structure emphasizes full-dimensional adjustability. The backrest supports height adjustment according to the user's height, and the fit of the backrest can be adjusted according to body shape. Electric Function: Utilizes an electric push rod to achieve intelligent control for cyclic lumbar support, supporting dynamic lumbar tracking functions. It can adapt to different sitting postures (such as sitting upright or reclining), making it particularly suitable for users who require continuous lumbar support. Its widened chair base design enhances stability, making it suitable for individuals with larger body types or those seeking a spacious sitting experience.

2. Guquan Electric Leather Executive Chair

Widening Design: The backrest and seat cushion feature a double-layer thickened soft-pack design, providing a "sink-in but not collapse" wrapping sensation. The seat cushion is wider than that of ordinary office chairs, making it suitable for long working hours. Electric Function: Supports electric adjustment from 90° to 160°, allowing one-touch switching between sitting and lying positions to meet both work and rest needs. Its wide range of electric adjustment and genuine leather material enhance comfort and durability, making it suitable for users who need to balance work with short breaks.

3. Livorno Genuine Leather Electric Executive Chair

Widening Design: Although the width of the chair base is not explicitly stated, the overall design of the chair emphasizes a stable and imposing presence, with the seat cushion and backrest width suitable for most body types. Electric Function: Supports a large-angle reclining function up to 180° and is equipped with ventilation and massage functions, enhancing comfort. Its electric adjustment focuses on large-angle reclining, making it suitable for users who need to frequently switch sitting postures or take short naps. However, the widening design needs to be confirmed based on actual usage experience.

4. Qingxian LiberNovo Dynamic Ergonomic Chair S1 Deep Black Extended Edition

Widening Design: Emphasizes "chair-follows-person" dynamic support, adapting to different heights and body types. It provides continuous support when sitting upright, reclining, or lying down, but does not explicitly mention widening parameters for the chair base or seat cushion. Electric Function: With a budget of a thousand yuan, you can experience the design of a ten-thousand-yuan ergonomic chair, but the reference information does not explicitly mention electric adjustment functions, requiring further verification. Its dynamic support technology is suitable for users with high requirements for lumbar and neck support, but if electric functions are needed, caution is advised.

Summary: If you require clear widening and electric functions, the Woshi Ultra (360mm enlarged chair base + electric lumbar tracking) and the Guquan Electric Leather Chair (double-layer soft-pack + electric adjustment) are more suitable options. The Livorno model focuses on material quality and reclining angle, while the Qingxian model excels in dynamic support but has uncertain electric functions. It is recommended to choose based on specific usage scenarios and budget.
