I like the pattern.  I like the color - as shown online.  I like the tread on the back to allow the tread to stay on the stair without tape or nails.  This allows them to be removed for easy cleaning.   We have vacuumed, broom swept and hosed down these treads all with success and no loss of color.  I would make sure you buy all you need in one package as we bought ours separately and there are slight variations between packages.  These are not your grandfathers stair treads (laughing).  Our guests love them and our elderly pets love them more.
