I got two of these that are in different sizes for a small guest bath.  They are pretty thick and comfortable to stand on.  My only complaint is on the larger of the 2 which tends to curve a little on the long side.  You can straighten it out easily, but after standing on it, it will have curved a little again.  It's not a big deal for me, but it might drive some people crazy.  I have not washed these, so I can't comment on how well they'll hold up to that, but they seem to be well made so I would think they'll do fine in that regard, too.
