The post from T. Glass doesn't cite a source. But I was able to find the following. URL where I found it below the quote.
"Katie said... I contacted Manhattan toys about the winkel. Here is their response. "Katie,
Thank you for contacting Manhattan Toy, The Winkel is manufactured with PU tubing. As such, it does not contain PVC (phthalates) or Polycarbonate (BPA). In general I can't say that all of our toys are BPA, and PVC free. I can say that our toys are safe and meet the safety requirements that are put forth by American Society for Testing and Materials (ASTM) and the European Union (EN71). If you have another toy you are inquiring about, please send me an email and I can let you know if it contains BPA, or PVC.
How on earth did we ever survive our own childhood? I cannot believe I survived without a bike helmet, a ski helmet, elbow and knee pads in a world filled with toxic plastic, toxic air, and toxic people.
