Very comfortable to stand on as expected.  We bought this one to match one we already had for use along the kitchen island.  The pattern is the same, but the color intensity is slightly different; not unexpected when you are dealing with a different dye lot, but it's not quite the same and they do lie next to each other.  And, as expected, it shifts on the floor when you use it.  But that is what these mats do, so we shift them back when needed.
