The parts do not stipulate what they are made off, but I believe it to be more fiberglass than anything else. For it is not a flexible material, like the original parts.

They appear to be a #7 plastic, which according to the internet is a catch-all category which makes it difficult to know exactly what the composition is. BPA, etc, can not be ruled out from this category of plastics. I wish I had asked the same question. Otherwise the quality is very good.

They must be plastic. They are marked "Not Oven Safe" They are marked "BPA Free". The do not appear to be as flexible as silicone and the center viewing window is a semi flexible clear plastic.

They're plastic. They're stiffer as well, not flimsy like the white and clear ones.

It's injection molded plastic. Not fiberglass. Very comfy though. It has a nice flex to it.

I'm about 99% sure they're microfiber. They definitely aren't terry cloth or just plain old cotton. Whatever they are, they absorb very well.

Neither, I believe they are nylon. Very durable and survive the Southern Arizona sun which let me tell you, isn't easy. I hope that helps.

I think it's molded plastic. It's definitely not fiberglass otherwise it would've been $300-$400 like Eames brand

I do believe they are made of Nylon. Very sturdy and solid. They worked very well. I felt very safe.

They are polyester with a urethane laminate. The shells are machine washable, but do wipe off pretty well. They breathe better than a plastic lined cover.

They are heavy plastic or vinyl. They are replaceable in the event that they wear out.

These are ceramic/glass - no BPA involved. BPA is a plastic issue or food-can-lining issue.
