Do not buy - a waste of $40!
I purchased this because I have a marble saddle going into the bathroom that is 1/4&#34; higher than my hardwood floors, always &#34;catching&#34; the wheels of my Dad's wheelchair.  This is nothing more than a piece of plastic - in fact, I had purchased place mats to put under the dog's bowls that are the same material.  This just gives you a larger area to get the wheelchair wheels stuck.  This is being returned.
