I'm looking for a supplier who can provide various types of beds. My interest spans different styles such as platform beds, bunk beds, and adjustable options. Please share your catalog or available models along with pricing details and lead times. Additionally, I'd appreciate info on materials used, customization options, and any certifications or standards your products meet. If you have any promotions or bulk order discounts, please include those as well. Looking forward to your prompt response!
