HF Office Chair Information

Information related to 'HF Office Chair' mainly includes product models, design features, and patent status, as detailed below:

I. Product Models and Prices
The HF series office chairs sold by Henan Wenhua E-commerce Co., Ltd. include two models:

1. HF-026 Office Chair: Priced at 749.00 yuan, specific functional parameters are not fully disclosed, but it is one of the higher-priced models in the HF series, likely targeting the mid-to-high-end market.
2. Haofeng HF-102 Office Chair: Priced at 475.00 yuan, it is relatively affordable and suitable for users with limited budgets.

II. Design Features and Functions

1. Hafu H5 Air-Sitting Health Chair: Although the brand name is not 'HF', the 'H5' in the model number may be related to 'HF'. This product features a '360-degree suspension' design, using only soft mesh fabric to contact the body, fitting the golden curvature of the spine, and providing comprehensive support for the neck, shoulders, waist, hips, and legs. Its SPA-level pressure distribution function can disperse the pressure from prolonged sitting, making it suitable for users who need to work for long hours.
2. Patent Design (Terminated): A product named 'HF-Ergonomic Chair 03' once applied for a design patent (application number CN202030406770.2), but the patent right was terminated on July 17, 2026, due to non-payment of annual fees. The patent may involve unique designs for the chair back, armrests, or base, but specific design details cannot be further verified due to the patent's termination.

III. Market Positioning and Selection Recommendations

1. For those seeking high-end comfort, the Hafu H5 Air-Sitting Health Chair is worth considering. Its suspension design and pressure distribution function can significantly enhance the sitting experience for long hours, but the direct relationship between the brand and 'HF' needs to be confirmed.
2. For cost-effective choices, the HF-026 or HF-102 models from Henan Wenhua E-commerce Co., Ltd. may be more suitable, with the HF-026 potentially offering more comprehensive functions and the HF-102 being more affordable.
3. Before purchasing, it is recommended to verify the product details page or consult the merchant to confirm parameters such as material, load-bearing capacity, and adjustment functions to avoid selection bias due to missing information.

IV. Precautions
'HF' may be a brand abbreviation or model prefix, and products from different manufacturers vary greatly. For example, the 'Xige' brand computer chair mentioned in the search results has no direct connection to 'HF' and should not be confused. Additionally, patent termination only means the loss of legal protection and does not affect the sales of existing products, but caution should be exercised against counterfeiting risks.
