Donut Cushion

A donut cushion, also known as a ring pillow or donut pillow, is a round cushion with a hole in the center, resembling a donut. It's designed to relieve pressure and provide support, particularly for the tailbone and lower back. They are commonly used to alleviate pain and discomfort from conditions like hemorrhoids, tailbone injuries, and sciatica, and can also improve posture.
