This is an awesome rug pad, doesn't scoot, makes rugs feel luxurious, and safe for wood floors (or carpet, I read).  This is our second, and the other has performed very well after 6 mo of heavy use.  Would be 5 stars but there is a weird garbage/chemical smell when you first unpack it (due to being recycled maybe??).  With the ceiling fan on high it dissipated after 1 day.
