So far, so good.  It fits where I need it at the moment and sleeps a whole lot better than the floor.  It is actually fairly comfortable, firm enough to walk on (if you need too) but cushiony enough to sleep on without a bad back in the AM.  I will eventually get a cot (or similar) to elevate it so it is easier to get in and out of, but for now, it's purpose is to save someone from injury if they fall out of bed.  Perfect
