I have a Tama First Chair round rider throne. I've had it for a few years but not that long. The PVC covering is splitting and looks like crud. I have some tape on one part but I look bad. I don't want to buy a throne cover and just hide the mess. It's past warranty I believe so Tama won't do anything about will they? I think it's because up here in Maine we get super cold winters, but also some hot humid days in the summer. Does temperature affect the PVC fabric? What would you do? Call a local upholstery place? Have any of you re-covered thrones before and what did you? And suggestions and advice would be appreciated guys!
