This is the most amazing soft and comfortable floor mat. It is 39×20 and comes up about 3/4 of an inch. I have never felt a rubbery but soft floor mat like this one. I absolutely love it and seriously move it around the house with me when I am cleaning. It now sit in front of the sink in my kitchen because its where i am standing the most. When I stand on this mat my feet dont ache and feel sore. Its like standing on a soft cloud. I am very happy with this product and would definitely consider purchasing again. I would also recommend this product to others. I received this product for free in exchange for my complete and honest review.
