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 published owner commentary (not independently verified).

Buying guide
When shopping for a pillow in this category, focus on loft, fill type, cover breathability, and trial period. Heavier sleepers usually need more support; petite sleepers often prefer lower loft.
FAQ
When should I replace my pillow?
Check its condition and comfort after permitted care. Permanent damage or an unsuitable fit can justify replacement; age and warranty length alone do not establish a useful life.
Does a higher price guarantee a better fit?
No. Compare the construction, available adjustments and return terms with what you need on your own mattress.
Can I machine wash my pillow?
Follow the care label for the exact pillow. Cover and fill may have different instructions; do not assume both can be machine washed.
