Office Chair Without Baseboard

Currently, no office chair products directly labeled as 'without baseboard' have been found, but some computer chairs do not emphasize the baseboard structure in their descriptions and may meet the requirements. The following models require further confirmation of details:

1. Bazhou Huobaotu Furniture Co., Ltd.'s 'Minimalist Backrest Ergonomic Staff Training Comfortable Computer Chair' (¥52.0)
   This product is characterized by minimalist design and does not mention the baseboard structure in its description, possibly adopting a baseboard-free or hidden design. Its core selling points are the ergonomic backrest and breathable mesh fabric, suitable for long-term office scenarios. However, it should be noted that low-priced products may have differences in structural stability, and it is recommended to prioritize confirming the connection method between the chair legs and the seat (such as whether it is an integrated design or an independent baseboard).

2. Bazhou Guangtonghui Furniture Factory's 'Computer Chair with Comfortable Backrest for Long Sitting, Gaming Chair, Ergonomic Office Seat' (¥61.75)
   This model is designed for both gaming and office use, emphasizing 'long-sitting comfort' and 'ergonomics' in its description, but does not specify baseboard information. It may replace the traditional baseboard with a thickened seat cushion or elastic support structure to reduce weight and improve breathability. It is necessary to confirm with the merchant whether there is metal or plastic frame support under the seat to avoid insufficient load-bearing capacity due to the lack of a baseboard.

3. Anji Zhike Furniture Co., Ltd.'s 'Gaming Chair, Ergonomic Gaming Chair, Internet Cafe Computer Chair, Home Reclining Office Chair' (¥112.44)
   This product is feature-rich, supporting multi-angle recline and reclining design, and does not mention the baseboard structure in its description. High-end gaming chairs often adopt an integrated steel frame or high-density foam seat, possibly omitting an independent baseboard to simplify the structure. However, it should be noted that the reclining function usually relies on the chassis adjustment mechanism, and the complete lack of a baseboard may affect stability. It is recommended to request the merchant to provide a diagram or video explanation of the seat bottom structure.

Purchase Recommendations:

• Contact the merchant first: Confirm through the product page customer service or phone whether the seat is designed with an independent baseboard or adopts a baseboard-free reinforced structure (such as an integrated plastic/metal frame).
• Focus on core parameters: Even without a baseboard, ensure that the chair legs (five-star legs) are firmly connected to the seat and that the load-bearing test data meets the standard (usually ≥100kg).
• Check user reviews: Focus on searching for keywords such as 'seat collapse' and 'structural wobble' to avoid products with design defects.
