I bought this as a runner for my long hallway - it is wonderful! I don't have a rug pad under it and it barely slides around; if it wasn't in a hallway and/or had furniture weighing down parts of it, I don't think the larger sizes of this rug would need a rug pad; I will be getting one for this hallway runner. The rug looks more expensive than it was. I have bought 3 rugs from Wayfair and they all look more expensive then they were, and I get compliments on them all the time. I highly recommend!
