I bought 2 sets  ( 4 rugs in all) of these durable red rugs for the holidays, to add a splash of seasonal color to my home.  The rugs have a firm (query) rubber grip feature on back which holds them in place well.  There is a little bounce when you step on them, so I guess that's the anti-fatigue feature, kinda nice. They are a neutral color, that I consider to be kind of a heather cranberry.  Price was very reasonable for these rugs.  I think they are GREAT!
