Rugable is beloved. When dirty, peel off the top layer and throw it in the washing machine. Beyond that, you can have any fiber provided you have the right pad under it. But an expensive wool will take a beating in the kitchen with liquid spills, crumbs, and dust from flour, sugar, cereal, etc.. You can find patio runners that can be hosed off outside, but again, gotta get the right padding. The raw backside of those would be slippery on tile, and rough on your hardwoods.
