I have an Ikea rug in my home office that I have been tripping over the last few years. One of its corners has a slight upward curl that is a magnet for tripping over. I spotted NeverCurl in a store, then ordered from Amazon. I was skeptical, but desperate. Well, I'll be damned if it didn't work. Quite well, in fact. I wouldn't say perfectly because it does make that corner slightly thick, which feels weird if you step directly on it, but it did solve the trip hazard. Recommended if you need such a thing.
