I am reaching out to inquire about pricing and availability for waterproof material suspension seats designed for excavators and tractors. Specifically, I'm interested in purchasing three pieces. It would be great to know if you have these in stock and what the lead time would be for delivery. Additionally, please provide details on any options for customization, such as color or additional features. If you have a catalog or data sheet available, that would also be helpful. Looking forward to your prompt response so we can move forward with this order.
