OneAid Relax Cushion M Size Purchased in September 2025 Used about 6 times, but selling because the size doesn't fit. I've taken care to clean it, but since it's a dog product, there may be some hair attached. Please understand. There is no instruction manual, only the Relax Cushion itself. Returns and complaints are not accepted. There is no major damage, but it is a used item. I look forward to purchases from those who understand this. ☆
