This model explicitly offers a 45cm standard version and falls under the category of ergonomic chairs. Its core design features include:

• Dynamic Adjustment Function: The total travel distance increases from 80mm to 96mm, and the total angle increases from 32° to 37°. It supports multi-dimensional adjustments of the neck pillow and armrests, and the backrest is optimized for fit through motorized adjustments, making it suitable for long-term office scenarios.
• Structural Parameters: The 45cm dimension may refer to the seat depth or width, and specific details should be referred to the product's detailed parameters. However, the overall design emphasizes support for the spine and waist to reduce fatigue from prolonged sitting.
• Applicability: Suitable for users who require dynamic adjustments to accommodate different sitting postures, such as programmers and designers.

2. 45 Chair (onecollection D005, Designer Finn Juhl)
This is a classic work by Danish designer Finn Juhl, falling under the lounge chair category and having a weaker direct connection to office scenarios:

• Design Style: It features a manchurian ash solid wood frame, leather upholstery, and high-quality foam filling, with dimensions of 700w (width) × 770d (depth) × 830h (height), focusing more on aesthetics and comfort.
• Functional Positioning: Suitable for family living rooms or leisure spaces, it is not a traditional office chair, but due to its classic design, some users may use it in creative office environments.
• Materials and Craftsmanship: The combination of solid wood and leather reflects Nordic design style, emphasizing the fit between natural materials and the human body's curves.

3. '45-Degree Office Chairs' on Alibaba Platform
These products are primarily described by function, with '45 degrees' typically referring to the recline angle of the backrest, rather than a dimensional parameter:

• Functional Features: Product titles often emphasize features like 'reclining' and 'ergonomic', with a wide price range (from 62.02 yuan to 634 yuan), covering basic to mid-range and high-end models.
• Dimensional Relevance: There is no explicit indication of a direct connection to '45cm', and specific parameters such as seat depth and width should be confirmed through the product detail page.
• Purchase Recommendations: If a 45cm dimension is required, it is essential to verify the product specifications first to avoid mispurchases due to keyword confusion.

Summary and Recommendations:
If a 45cm office chair is needed, the Qingxian LiberNovo Omni Dynamic Ergonomic Chair is a clear choice that meets the requirements, with its ergonomic design and dynamic adjustment functions better suited to office needs. If design aesthetics are pursued, the 45 Chair (onecollection D005) can serve as a supplementary option for leisurely office use.
