Fixed Green Office Chair

Currently, there are no explicitly mentioned models of completely fixed and non-adjustable green office chairs on the market, but some basic models or fixed-structure versions of ergonomic chairs may meet the requirements. Here is a detailed analysis:

1. Sihoo M56 Second-Generation Ergonomic Chair (Green Series)
This model primarily features a basic fixed structure, with its core function being precise lumbar support. It is suitable for users with a limited budget who seek basic comfort. Its design may not include dynamic adjustment modules (such as height or angle adjustments for the headrest and armrests). However, it should be noted that 'ergonomic chairs' generally come with a certain degree of adjustability by default, and it is necessary to confirm whether they are completely fixed through product parameters. If users have no requirements for adjustment functions, this model may be close to the 'fixed' requirement, but further verification is needed.

2. Green Office Chair Brands and Materials Available on the Market
Brands such as Tengliang Technology, Xinnuo Furniture, and Lvyisen offer green office chairs, with materials including artificial boards, metals, and particle boards. These products are mostly designed as traditional office chairs and may primarily feature fixed structures (such as fixed armrests and fixed backrest angles), but this needs to be confirmed through specific model parameters. For example, some budget-friendly office chairs may adopt an integrated design without adjustment functions, but it should be noted that the material may affect comfort (such as the poor breathability of artificial boards).

3. Qingxian LiberNovo Dynamic Ergonomic Chair OC1 Limited Edition (Green)
This model focuses on dynamic support functions (such as adaptive lumbar support and adjustable headrests). Although it offers a green limited edition version, it falls into the category of adjustable ergonomic chairs and does not meet the requirement for a 'completely fixed' chair. If users need a fixed structure, this model is not recommended.

Purchase Recommendations

• Confirm Fixed Characteristics: Prioritize models that are explicitly labeled as 'non-adjustable' or 'fixed structure' in the product description, or verify specific parameters (such as whether the armrests, backrest, and headrest are adjustable) through the brand's customer service.
• Pay Attention to Material and Comfort: For fixed-structure office chairs, it is necessary to consider the impact of materials on long-term use (such as the durability of metal frames and the better breathability of mesh backrests).
• Basic Ergonomic Requirements: Even when choosing a fixed structure, ensure that the chair meets basic ergonomic requirements (such as lumbar support and reasonable seat depth) to avoid health issues caused by the fixed design.

If you need to further narrow down the options, it is recommended to directly contact the brand or consult the detailed product manual to confirm the adjustment functions and fixed characteristics of specific models.
