This mat is a work of art! It's actually a bit thicker than 1-1/2 inches. I 'danced' this thing outside our front door. Wrapped in plastic. No tears or holes in plastic. Looks so pretty on our porch. I expect to have this for many years to come. The dye looks very well done. There were some slight 'fibers' in the bottom of the plastic from shipping. The tag says the product is "coir". It's the outer part of a coconut that has been soaked to make it stronger. Can't believe how heavy it is. Maybe 30 lbs? Would recommend and buy another if needed. I know it's pricier than others; but I know you will not be disappointed.
