Amazon Foam Variation Setup

I want to launch a single parent listing on Amazon that lets shoppers choose any custom-cut foam they need. The listing has to accommodate every size, from basic straight rectangles to tight curved corners and even complex shapes, and it should make clear that the foam can be used for cushions, packaging or insulation alike.

Here is what I expect:
• A fully compliant parent-child variation structure uploaded through a flat file (or directly in Seller Central if that is faster) so customers can select their exact cut requirements in one place.
• Accurate variation attributes mapped to Amazon’s size model, with the product title, bullet points and description tailored to highlight “custom cut foam” as the key choice.
• Back-end search terms and category nodes optimised for cushions, packaging and insulation keywords.
• Image and content guidance that demonstrates the different shapes and uses without breaking Amazon’s rules.

Once the listing is live, I should see all SKUs properly linked under the parent, no suppressed variations, and an intuitive dropdown that reflects every possible size or shape combination.
