Ergonomic Millet Knee Pillow for Side Sleepers with Lower Back, Hip or Knee Pain
Waking up with hip or lower back pain is common for side sleepers—and poor leg alignment is usually the cause. The PineTales Knee Pillow is designed to keep your hips level and your spine naturally aligned by gently separating your knees. It works as a breathable, supportive spacer between your legs, reducing tension and helping you maintain healthier posture all night long.
Unlike foam or bulky leg pillows that trap heat and lose their shape, our millet-filled knee pillow stays cool, adapts to your body, and won’t flatten out. It’s fully adjustable, compact enough to travel with, and made only from safe, natural materials. Whether you call it a side sleeper knee pillow, between-leg cushion, or orthopedic spacer—it delivers real relief and better sleep and is highly recommended by us to be used in combination with any of our buckwheat pillows or millet pillows for full sleep posture optimization.
Available sizes: 10″ × 2.5″ and 12″ × 2.5″

Frequently Asked Questions
Why should I use a knee pillow?
If you're a side sleeper, a knee pillow is essential for proper sleep posture. It aligns your hips, pelvis, and spine by preventing your top leg from twisting forward. This simple alignment can significantly reduce pressure on your lower back, hips, and knees, leading to less pain and a more restful night.
How do I position it correctly?
It's easy. While lying on your side, simply place the pillow between your knees. The ergonomic shape is designed to fit comfortably and stay in place, keeping your legs parallel and your spine properly aligned all night.
Can't I just use a regular pillow?
Regular bed pillows are too soft and bulky; they flatten overnight and shift out of place, failing to provide consistent support. Our knee pillow is specifically shaped and filled with moldable hulls to stay securely between your legs and maintain its supportive structure all night long.
Is it adjustable?
Yes. We believe in customized comfort. The durable YKK zipper allows you to easily add or remove the natural hull filling to achieve the perfect thickness and firmness for your body.
How do I clean it?
To clean, unzip both the inner and outer covers and empty the hulls into a clean container. You can then machine-wash both fabric covers on a gentle cycle. To refresh the hulls, simply let them air out in the sun for a few hours before refilling. Important: Never get the hulls wet.
