I bought four of these rugs to help me stand on a tile kitchen floor. i like them because the edges are tapered and are not a tripping hazard. they help when i stand at the kitchen counters for an extended period by taking the stress off my back. i wish they gripped the floor a little better. they dont slide when stepping on and off of them, but i sometimes use a walker in the kitchen, and if the wheels of the walker catch on the edge of the rug, the rug will slide out of place.
