The carpet is great! First we turned it upside down and placed heavy books on the edges.The next day almost all the roll marks and curl were gone ,we placed it upright and a few days later ALL roll marks gone. The dark grey contrasts nicely with light grey walls. The yarn colors are variegated  enough so crumbs are not readily seen... I'm not constantly vacuuming! I am very pleased with this carpet. I would recommend it to a friend! The 7ft 10in diameter is perfect for the 48in.round table.
