Common models of Deli office chairs include Deli 4901, Deli 4901S, Deli 91108, the Deli 4900 series (including 4900, 4900S, 4900M), and variant models such as 91103. Here is a detailed introduction to each model:

Deli 4901 and 4901S
These two models belong to Deli's classic office chair series, focusing on basic functionality and cost-effectiveness. The 4901 typically comes with an adjustable headrest, fixed armrests, and a pneumatic height adjustment feature, making it suitable for daily office use. The 4901S, as an upgraded version, may feature optimizations in materials or adjustment details, such as using more breathable mesh fabric or adding a lumbar support adjustment function to enhance comfort during prolonged sitting.

Deli 91108
This model is positioned in the mid-to-high-end market, with a design that emphasizes ergonomics and functionality. Its core features include multi-directional adjustable 3D armrests, a synchronous tilt mechanism (where the backrest and seat tilt in tandem), and a high-density foam seat cushion, making it ideal for users who need to work at a desk for extended periods or frequently adjust their sitting posture. Some configurations may include a breathable mesh backrest to enhance the summer user experience.

Deli 4900 Series
This series includes the basic model 4900, the upgraded model 4900S, and the conference mesh chair variant 4900M.

• 4900: The basic model, equipped with pneumatic height adjustment, fixed armrests, and basic lumbar support, is suitable for budget-conscious users who need to meet basic office requirements.
• 4900S: An upgrade over the 4900, it may feature an adjustable lumbar support, a more durable five-star base, or a thicker seat cushion to enhance durability and comfort.
• 4900M: Designed specifically for conference settings, it adopts a full mesh structure for excellent breathability and has a fixed backrest angle for easy uniform placement by multiple users, making it suitable for conference rooms or training rooms.

Other Variant Models (such as 91103)
These models are typically developed for specific needs or niche markets. For example, the 91103 may focus on lightweight design or simplified adjustment functions to lower the price barrier, making it suitable for budget-sensitive users or temporary office settings.

Purchase Recommendations: If basic functionality is required, the 4900 series is a good choice; if ergonomic design is pursued, the 91108 or 4901S would be more appropriate; for conference settings, the 4900M should be given priority. It is recommended to make a comprehensive decision based on usage frequency, budget, and functional requirements.
