I have this rug in two sizes.  The larger one, I have no issue with.  But the smaller one tends to curl up on the ends and tends to slip and slid on the floor.  I have tried different devices to prevent slipping, but nothing seems to work.  The larger one, because of its heavier weight does not slip.  I have tried to get a larger size to replace the smaller one, but that size has been out of stock for quite some time.  I was told that I would be notified when a larger one was available.  I don't know if Wayfair failed to notify me, or if it is still out of stock.
