Shuangta Office Chair

Currently, no standardized product explicitly named 'Shuangta Office Chair' has been identified, but there are procurement cases and second-hand market resources related to 'Shuangta' office chairs. Here is the specific information:

1. Procurement of Tianwei Brand Office Chairs in Medical Projects
In the new construction project of Shuangta Hospital in Chaoyang City, various office chairs from the Tianwei brand were purchased, but none were named after 'Shuangta'. For example:

• Pre-shift Chair (TW-77GZ): Bow-shaped design, dimensions 580mm×740mm×970mm, unit price 196 yuan, suitable for reception or temporary office scenarios.
• Swivel Chair (TW-52ER): Adjustable height design, height range 980-1080mm, dimensions 600mm×660mm, unit price 228 yuan, suitable for positions requiring flexible adjustment of sitting posture.
• Podium Chair (TW-95SP): Dimensions 630mm×500mm×1000mm, unit price 294 yuan, typically used for meetings or speeches, emphasizing stability and a sense of ceremony.
  These products are named based on their functions and do not reflect the 'Shuangta' brand or design characteristics. They may be associated with the Shuangta District institution as the purchaser.

2. Idle Resources in the Second-hand Market
On platforms like 58.com, there are second-hand office chair transaction listings in Shuangta District, but most are general-purpose products posted by individuals or merchants, such as '90% new office desk and chair sets', without explicitly labeling them as 'Shuangta Office Chairs'. Prices for such resources vary widely, and the style and condition need to be confirmed on-site, making them suitable for scenarios with limited budgets or temporary use.

3. Indirect Association in the Design Field
The BAIANA Rattan Ziza Chair designed by architect Álvaro Siza reflects modern aesthetics through geometric proportions (armrests 13.5mm, chair legs 27mm, seat supports 40mm), but it belongs to high-end art furniture and has no direct connection with 'Shuangta'. This case illustrates that while mathematical logic may be incorporated into office chair design, 'Shuangta' is not used as a design element here.

Summary
If you need to purchase office chairs, you can refer to the Tianwei brand products from the Shuangta Hospital project and select models based on functional requirements. If you are looking for cost-effectiveness, you can pay attention to second-hand market resources. If you are interested in design aesthetics, you can explore international brand cases, but note that 'Shuangta Office Chair' is not a universal term in the industry, and specific products should be selected based on the scenario and budget.
