Best Knee Pillows for Hip and Back Pain
When you sleep on your side, your top leg slides forward and pulls your pelvis into rotation — and that twist travels straight into your lower back and hips. A knee pillow restores the stack: knees together, hips level, spine neutral. Physical therapists routinely suggest them for sciatica, hip bursitis, pregnancy hip pain, and post-surgery positioning. The picks below are contoured memory foam designs that stay between your knees all night, including one with a leg strap for restless sleepers, plus a body pillow option if you want full-length support. These are research picks based on manufacturer specifications and verified owner feedback.
