I used it only once with the cover on. The height didn't suit me, so I'm selling it. It's in almost new condition, and the filling can be taken out and put back in, but I haven't changed anything from the original state. It's a clean item, but it is still a used item, so please refrain from purchasing if you are sensitive to this. Due to its size, it will be shipped folded in half. - Model Name: Neck Fit (P2212) - Adjustment: Height adjustable - Material: Pipe/Polyester - Features: Low adjustment possible
