澳大利亚采购需求：电动可调节高度办公桌

I'm in the market for tables and chairs that can accommodate 70 people for various settings. Specifically, I need adjustable conference tables, as well as dedicated tables for managers and CEOs. These will be used in both the pantry and meeting rooms, so versatility is key. Please provide options that fit these requirements, including any recommendations you might have for durable materials or designs suited for a professional environment. Looking forward to your response with relevant details and pricing.
