美国采购需求：治疗

I'm looking to source a custom back stretcher that meets specific ergonomic requirements. Ideally, it would be designed to provide targeted support and relief to the lower back, while being easy to use at home or in a therapy setting. The material should be durable yet comfortable, ensuring it can withstand regular use without losing shape or effectiveness. Additionally, I need the design to be compact for easy storage and transportation. If possible, it would be great to have options for different settings, like adjustable intensity levels or additional features that enhance the user experience. Please share your capabilities in creating such a product, along with any existing designs or custom options you might have in your portfolio.
