Deli 4901 Office Chair

The Deli 4901 office chair is a cost-effective mesh swivel chair launched by Deli Group, suitable for office settings and recognized by users for its substantial build and reliable quality.

Product Basic Information
The Deli 4901 office chair (some models are labeled as the 4901S ergonomic computer swivel chair) is made in mainland China and has a gross weight of 11.9kg. As of May 2025, the market reference price is approximately 269 yuan, making it a solid choice among budget-friendly office chairs with relatively robust configurations. Its core design revolves around "mesh breathability" and "basic ergonomics," making it suitable for long hours of office work.

Features and Structural Characteristics

1. Pneumatic Height Adjustment Design: Equipped with a standard pneumatic rod, it supports seat height adjustment to accommodate users of different heights and desk heights, offering convenient operation and good stability.
2. Seat Dimensions: With a seat width of 45cm and a seat depth of 47cm, it falls into the medium-to-large size category, providing ample sitting support space and reducing fatigue from prolonged sitting.
3. Mesh Material: The chair back and seat are made of breathable mesh fabric. Compared to traditional leather or sponge materials, it is less likely to cause stuffiness in summer and has moderate elasticity, distributing pressure more evenly on the waist and buttocks.
4. Basic Ergonomics: The chair back provides a certain degree of curved support to help maintain a natural sitting posture, but it is not equipped with an adjustable lumbar support or headrest, making it suitable for daily office scenarios with low functional requirements.

Installation and Accessories
The product adopts a modular design, with installation components including 1 chair back, 2 armrests, 1 seat, 1 pneumatic rod, 1 chair base, 1底盘 (which can be translated as "seat plate" or kept as "chassis" depending on context, here we use "chassis" for clarity), and 5 chair wheels. Users can assemble it themselves according to the instructions, and the process is relatively simple, requiring no professional tools. The chair wheels are silent omnidirectional wheels, suitable for movement on wooden floors or tiled floors.

After-Sales Service
Deli provides a nationwide warranty service for this product. Users can inquire about repair or return and exchange issues through the after-sales service hotline 400-185-0555. Please note that warranty policies may vary slightly depending on the sales channel or region, so it is advisable to confirm the specific terms when making a purchase.

Applicable Scenarios and Limitations
The Deli 4901 office chair is suitable for small and medium-sized enterprises or home office users with limited budgets who pursue basic comfort. If more advanced ergonomic adjustment functions (such as adjustable lumbar support or armrest angles) or a longer warranty period are required, consider high-end models from the same brand or other professional ergonomic chair brands.
