I'm reaching out to inquire about the ergonomic office chair featuring an all-mesh design and a headrest for enhanced comfort. I'm particularly interested in understanding the specifications, including material quality, available color options, and any unique features that set this chair apart in terms of usability and support for long hours of sitting. Could you also provide details about the minimum order quantity, pricing structure, and lead times for production and delivery? Additionally, I'm keen to know if you offer any warranty or after-sales services. Please send any relevant catalogs or brochures that showcase this item and other similar products you might have. Looking forward to your prompt response.
