1. Quick Answer
A leg pillow for sleeping is an ergonomic cushion designed to be placed between or under the legs to maintain pelvic alignment and reduce pressure on the lower back. It primarily suits side sleepers seeking improved spinal neutrality and back sleepers needing knee elevation. However, its effectiveness is highly subjective, and it may feel restrictive to those who move frequently during the night.

6. Limitations and Considerations
A leg pillow is not a universal solution for sleep issues. It is not suitable for all sleeping positions; stomach sleepers, for example, will find no benefit and likely more discomfort. Personal preference regarding foam density is the biggest variable in satisfaction. Furthermore, a pillow is a comfort aid and provides no guarantee of improvement for underlying chronic issues.
