Oops, I must have measured wrong as the rug is too big for its intended space.  The rug comes tightly rolled up in a sleeve of plastic.  I will use the innermost, tightly wound end up against the wall behind a door to make it fit.  I question that this tightly rolled end will ever lie flat, but I did not try working with it.  

I think that the .5 inch thickness of this rug is probably the minimum thickness that one would want to order and still have a softness to the step. This thickness allows a door to pass over it.

Pros: beautiful color
