All,
I have newly re-finished pine floors and know I need to be careful about using rubber-backed carpets directly on the wood. I need to find a low-profile door mat / carpet to place in the entry way to my house. Any suggestions for what kind of backing the mat / rug can have? I found several styles which might work: "dirt trapper" with a Non-skid latex backing at ProblemSolvers --- Low Profile Custom Water Trap Mat with a Anti-slip rubber backing from Brookstone --- Waterhog Mat with an Anti-slip rubber backing from Brookstone ---
I would like something that is safe to use on my wood floor. Machine washable would be a real plus besides.

Thanks ahead of time for all the good suggestions !!
