Bests & Worsts Reviews from Amazon

I got this thinking it was a beautiful eco friendly option. Then I did research on PER, and it seems to be processed PVC, that can biodegrade, however, biodegradable plastics are also under the same category of plastics that break down into extremely small particles that aren't organic, but in fact small pieces of plastic.... Creating plastic that's impossible to clean up, polluting the soil and water. I e-mailed the company asking about this but haven't gotten a response. I'll definitely be getting my money back on this one unless I figure out what my research shows is wrong. I'll probably look for an ethically harvested natural rubber mat only, after the research I've done.
