I was looking at the install video of this. Are the ribs that level the matt foam or fabric? What it the top material like? It looks like a fabric but says its made out of Polypropylene, which isn't that a form of plastic?
The ribs are a foam type material and the upper surface is a tough plastic material. If you want to bolt through the bed you could shave off a section of the foam and put a strip of wood in its place. https://photos.app.goo.gl/vck2T8q2J4cf7vma6
