乌干达采购需求：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 a high-quality black office chair that provides comfort and support for long hours of use. It should have adjustable features, including height and armrests, to cater to different users. Durability is also important, so materials that can withstand regular use are a must. Additionally, I'd like to know about the design options available. A modern, sleek aesthetic would be preferred to match our office environment. Please include details on the pricing, minimum order quantity, and lead time for delivery. I'm eager to explore suitable options for our team. Thank you!
