I'm reaching out to inquire about height-adjustable desks with electric functionality. I'm particularly interested in exploring various models and specifications your factory offers in this category. Could you provide detailed information on the different sizes, weight capacities, and any adjustable range options? Additionally, I'm curious if you have options for customization or specific features that set your products apart from the competition. Furthermore, it would be great if you could share any available certifications or quality standards that your products meet, as well as pricing details and bulk purchase options. Understanding the lead times for production and shipping would also be helpful. Looking forward to your prompt response so that we can potentially move forward with an order soon!
