I ordered two of this area rug.  One for the dining area, under table and chairs on hardwood floor and one for a hall area on carpet.  Under my table and chairs I did not want "loft", just to define the area on the hardwood floors, this collection's look is perfect.  Lays flat and smooth, chairs move easily for diners. In the hall area on the carpet it does 'creep' just slightly.  As I have several true Turkish and Persian carpets I am used to the slight tug on this or that corner to keep them straight.  The  look of these area rugs goes great with the true carpets.      Pros: Lays flat and smooth, easy to move dining chairs in and out to the table, very low nap. The color variation is much like my hand tied silk carpets.Cons: None at this time.  The rugs have only been on the floors a week.
