I'm looking for a wheelchair-accessible model that meets a variety of needs. It's essential that the design provides easy access and comfort for users who require assistance. I would appreciate it if you could share more details about the features, materials, and any customization options available. Additionally, I'm interested in understanding the pricing structure, lead times for production, and any bulk purchase discounts you might offer. It would be great to know about the warranty and after-sales support as well. Please include any relevant specifications and a catalog or documentation that outlines the options you offer for wheelchair-accessible models. Looking forward to your prompt response!
