英国采购需求：游戏桌、办公椅轮子、最佳人体工学办公椅、真皮办公椅、家用办公椅、舒适办公椅

I am reaching out to inquire about a specific model of office chair that comes with a footrest feature. I'm interested in understanding more about the materials used, as well as the available color options. Additionally, could you provide information on bulk pricing, shipping details, and estimated delivery times? Also, I'd like to know about any warranty options or after-sales services that your factory offers. It would be helpful if you could share any relevant product specifications or brochures. I'm looking to potentially place a sizable order, so any additional details that could assist me in making an informed decision would be greatly appreciated. Thanks!
