If you take a look at the back of the carpet, it has a plastic like look to it. The flat carpet is heated up and pressed into the mold. When it cools a bit, the plastic looking back hardens and that is what forms the shapes. Being careful, you can easily massage ill fitting areas yourself with a heat gun and some patience. With the heat gun on low, warm up the back of the carpet until it is soft and pliable. Then, using some slightly damp towels, press on the area to form it better. It will work, just be patient.
