Quick Answer
A knee pillow for sleeping is an ergonomic support tool, typically made of high-density memory foam, designed to be placed between the legs for side sleepers or under the knees for back sleepers. It may suit individuals looking to improve their nighttime posture and general sleep comfort. However, its effectiveness is subjective, and it is not a medical treatment for chronic pain or underlying skeletal conditions.
What Is a Knee Pillow for Sleeping?
