I bought the product because I bruise easily and after losing a lot of muscle mass recently, the weight of one leg on top of the other while I slept was leaving me with bruises inside my knees and shins. I toss and turn and though pillows feel good when I'm going to sleep, they never stayed in place.I measured twice and ordered once. Even so, the sleeve seems to be too big as both the top and bottom edges have too much material to conform to my leg but the part around the actual knee fits well and the whole thing stays in place. After two months, the padding has compressed a little but it still works well enough at distributing the weight of my leg so there's no bruising.
