Admin October 09, 2026
If you are looking for a comfortable office chair, several seadog chair models from Areffa and Shanfei are worth considering. Here are specific recommendations and feature analyses:

Areffa Seadog Chair
- Classic High-Back Seadog Chair: The seat height is 30cm, seat width is 47cm, seat depth is 41cm, and backrest height is 56cm. Its design focuses on fully conforming to the back curve, providing ample support for the neck and waist through ergonomic curves, making it especially suitable for long hours of office work. This support reduces muscle fatigue caused by prolonged sitting and lowers lumbar pressure.
- Multi-Adjustable Seat and Recline Model: It offers four adjustment levels. Level 1 is suitable for sitting while eating or working, Level 2 is ideal for short naps, and Levels 3-4 can meet the needs of afternoon naps. The height-adaptive design is a highlight of this model: individuals under 1.7 meters are recommended to choose the short-leg version, while those over 1.7 meters should opt for the tall-leg version. By adjusting the leg support ratio, it alleviates blood circulation pressure in the legs during prolonged sitting.
- Enlarged, Widened, and Heightened Model: Optimized for taller individuals, this model features larger seat width, depth, height, and backrest height compared to standard models, providing more spacious sitting and lying space. When adjusted to the appropriate angle, it can meet the needs of resting with head support, semi-reclining, or fully lying down, catering to both office and rest scenarios.
Shanfei Seadog Chair
- Basic Backrest Four-Level Adjustment Chair: Priced at around 200 yuan, it offers excellent cost-effectiveness. Its backrest supports four-level adjustment, providing high comfort in semi-reclined mode, suitable for users with a limited budget who seek basic adjustment functions.
- Premium High-Back Model: Compared to ordinary Kermit chairs, it is smaller in size and upgraded in material, with a fabric made of double-layer thickened Oxford cloth, offering better wear resistance and breathability. The high-back design further enhances neck support, making it suitable for office scenarios with higher requirements for material and space occupation.
Purchase Recommendations:
- If you need to work long hours and prioritize waist support, choose the Areffa classic high-back chair first;
- If you need multi-scenario use (such as afternoon naps), the Areffa adjustable model or Shanfei premium model is more suitable;
- If you have a limited budget and low demand for adjustment functions, the Shanfei basic model is a cost-effective choice.
