I'm reaching out to inquire about your range of collapsing chairs. I'm particularly interested in understanding the specifications, materials used, and available designs. It'd be great if you could provide detailed information on weight capacity, dimensions when folded, and any unique features that make your product stand out in the market. Additionally, I'd appreciate it if you could share your pricing options for bulk orders, along with any potential discounts or lead times for large quantities. If there are any certifications or quality assurances associated with these chairs, please highlight those as well. Looking forward to your prompt response so we can discuss potential collaboration opportunities.
