The mat looks like it does in the picture and the picture is very nice.
It stays put on the floor and I do not have any kind of pad underneath.  
The mat washed beautifully in the washer on a gentle cycle.  I did not put  it in the dryer but let it air dry.
My only complaint is that I wish the mats were a little thicker.  They do provide some cushioning when you stand on them, but nowhere near as much as the gel mats I used previously.
