I'm not quite sure why all the positive reviews for this rug (which is unfortunately why I ordered the rig in the first place). It's VERY thin and the bottom of the rug is covered in a cheap plastic material that makes it lumpy and bumpy. It's nearly impossible to smooth out the bumps because of this. Corners constantly curl up, even with multiple attempts to flatten them down with heavy objects and rug corner tape. Just can't get over how thin this is!
