In the first week I had this cover all the stitching in the seat area came undone. The elastic hem ensures the cover falls halfway down with you when you step out. I'm not a heavy or tall person. I left the seller a review but never heard a word. I was also disappointed that the cases, despite advertising as an American company, are made in China. I bought the UR Power Case for $16 and it's much better so I ordered a second one. Firmer fabric, tighter fit, stays in place!
