Quick Answer
A sleep pillow between knees is a specialized cushion designed to maintain pelvic alignment and reduce strain on the lower back for side sleepers. It suits individuals looking for improved nighttime comfort and those who experience hip or back pressure while sleeping. However, its effectiveness is subjective; it is not a medical device, and some users find it cumbersome or restrictive during movement.
