非洲地区采购需求：现代办公椅，办公椅，产品，培训椅

I'm interested in sourcing a variety of office chairs suitable for ergonomic use. Could you provide me with details on available models, including materials, color options, and pricing? I'm particularly looking for chairs that offer good lumbar support and adjustable features. Additionally, please include information about your minimum order quantities, lead times, and any bulk discounts. It would be great if you could also share specs or brochures for your bestsellers in this category, as I want to ensure we choose the right fit for our office needs. Looking forward to your prompt response!
