I bought mine from a horse feed/tack store. Sounds strange but these wool mats are also used under horse saddles and come in larger sizes. They are new from the manufacturer (not used on a horse or in a barn) and have no odor. I have a quilters ironing board made by my husband, so I have to use two of them for the length. They have never given me a problem. Mine came from
www.statelinetack.com and was under $30 each.
