I bought one 9'x12', one 4'x6' and two 2'1"x6' Connie Champagne/Cream rugs a few weeks ago. The 9'x12 still has ripples and although not as extreme as when originally unrolled....I'm not confident that it will eventually lay down. The other 3 rugs have relaxed flat. One of the two runners is not square on one side but tucked under an end table so not too noticeable. They all came in a timely manner and I'm happy with the variations in color. I used the "Deluxe Dual Surface Non-Slip Rug pad (0.25") under all and they don't move around. If the larger rug doesn't lay down, I will probably replace it sooner rather than later with a bit thicker rug but good for a quick solution in a new home during covid lock downs. The rugs are thinner than I hoped for but good for the price and delivery speed.
