Quick Answer
A pillow to put between legs when sleeping is an orthopedic sleep aid designed to maintain pelvic and spinal alignment for side sleepers. It may suit individuals experiencing lower back pressure, hip discomfort, or those seeking better posture during rest. However, its effectiveness is highly subjective; it is a comfort tool, not a medical device, and does not guarantee the resolution of underlying health conditions.
