南苏丹采购需求：办公椅，办公桌，办公沙发，文件柜，学校家具，培训家具

I'm looking for details on a range of office chairs that your factory offers. Specifically, I'm interested in information regarding the various designs, materials, and ergonomic features available. Additionally, can you provide insight into the customization options, such as colors and finishes? It would be great to know about any bulk pricing or discounts for larger orders as well. Also, I'd like to understand your production lead times and whether you have any certifications for quality standards. If you could send over a catalog or a product list with images, that would be super helpful. I'm keen to explore what you have to offer and see if we can establish a potential partnership moving forward. Looking forward to your response!
