Last updated: October 18, 2026 8:00:00 AM
Quick Answer
Sleeping with a pillow between the knees is a sleep posture technique used primarily by side sleepers to improve spinal alignment and lower body comfort. By placing a specialized or standard pillow between the legs, users can prevent the upper leg from pulling the spine out of a neutral position.
While it may suit individuals looking to reduce hip or lower back pressure, its effectiveness is highly subjective. A key limitation is that it is generally only beneficial for side sleepers; back or stomach sleepers will likely find it intrusive or counterproductive to their sleep quality.
