Memory Foam Knee Pillow

A knee pillow sits between your legs when you sleep on your side. It keeps your knees apart and stops the top leg from dropping forward. Doctors and midwives suggest a pillow between the legs in a few situations, such as pelvic pain in pregnancy and after hip replacement surgery.

This guide covers when a knee pillow helps, what to look for, and seven memory foam pillows to compare.

General information, not medical advice; talk to a doctor if you have ongoing pain, or follow your surgeon’s instructions after surgery.

Buying Considerations for a Memory Foam Knee Pillow

Pick a pillow whose height matches the gap between your knees when you lie on your side. A pillow that is too thin lets the top knee drop, and one that is too thick pushes the hip up.

• Shape – Dual concave or hourglass pillows cradle both knees. Heart-shaped pillows sit between the knees only. Wedges raise the legs.
• Size – Check the stated dimensions. Larger pillows suit wider hips and longer legs.
• Strap – An adjustable strap keeps the pillow from slipping when you turn.
• Cover – A removable, machine-washable cover is easy to clean, and a breathable cover is cooler.
• Foam – High-density memory foam keeps its shape. Ventilated or channeled foam lets air through.
• Certifications – OEKO-TEX Standard 100 covers textiles, and CertiPUR-US covers foam.

When a Knee Pillow Helps

The NHS suggests putting a pillow between your legs for extra support in bed if you have pelvic and lower back pain in pregnancy.^[2] For hip pain, the NHS says to see a GP if the pain stops you doing normal activities or affects your sleep, or has not improved after 2 weeks of treating it at home.^[1]

After a hip replacement, AAOS says your doctor may ask you to avoid certain sleeping positions or to sleep with a pillow between your legs for a period of time.^[3] Ask your surgeon before you buy one, because the recommended size and period depend on the surgery.

A leg wedge such as the Abco Tech is for raising the legs, not for between the knees. The NHS suggests raising swollen ankles, feet or legs on a chair or pillows when you can.^[4]

We looked at these factors:

• Shape – Dual concave, hourglass, heart or wedge.
• Size – Stated dimensions and length.
• Foam and Cover – Memory foam type, airflow and washable cover.
• Extras – Strap, certifications and warranty.
