I have a couple on the floor. One has a felt backing and the other is backed with short-pile, tight weave-carpet. I prefer the felt. My wall zebra (taken in Tanzania) is a pedestal wall mount. Those zebras do not have shadow stripes. The contrast therefore, is striking. I do have bear rugs on the wall but, no zebras.
