The item description said the pad would protect the table from heat up to 320 degrees F; however, the info on the packaging only mentioned stain & spill protection.   
 The pad appears to be a vinyl table cloth and is very thin; although, the online description said it was a heavy-gauge vinyl with felt backing.  It I don't want to keep this item if it doesn't protect from heat/cold and don't want to pay to return it.  What can you do to help?
