This is a Nitori high-resilience round cushion. It's in relatively clean condition. I bought it about six months ago and have used it a few times. I washed the cover before listing it. It fits the shape of your buttocks and supports your posture. A cushion that makes it less likely to hurt even when sitting for long periods.
