“Placing a pillow between your legs when lying on your side may help by preventing the hips from tilting or rotating. This simple adjustment may ease lower back, hip, and even knee pain for some people. To get the most benefit, choose a pillow that’s firm enough to support your legs but not so thick that it forces your hips out of a neutral position.”

Have you ever tried sleeping with a pillow between your legs? It may seem unusual at first, but this simple trick could be the secret to a more comfortable, deeper sleep. Whether you’re dealing with back pain, restless nights, or just want to feel more supported in bed, here’s why this sleep trend is worth trying.

The benefits of sleeping with a pillow between your legs

Sleeping with a pillow between your legs offers a wide range of benefits, such as:

1. Better spinal alignment and posture

Placing a pillow between your legs helps keep your spine neutral, especially if you sleep on your side. It prevents your top leg from pulling your spine out of alignment, which studies show may reduce back or hip pain and improve posture.

2. Joint and pressure relief

Sleeping with a pillow between your legs provides cushioning that reduces pressure on your knees, hips, and ankles. This is ideal for people with joint pain, arthritis, or if you’re one of the 23% of the global population who experience back pain.

By providing your joints with extra support, you create a more comfortable sleep environment and may wake up feeling more refreshed. Our article about whether there’s a link between sleep problems and musculoskeletal health provides more information if you want to learn more.

3. Improved blood circulation

Placing a pillow between your knees can promote better circulation by relieving pressure on blood vessels, which may help prevent numbness and reduce the risk of varicose veins.

4. Alleviated knee pain

Side sleepers often find their knees rub together at night, which can lead to discomfort. Sleeping with a pillow between your knees creates a soft barrier, helping to reduce friction and discomfort.

5. Hip and pelvic support

Sleeping with a pillow between your knees can keep your knees apart and prevent pelvic rotation during sleep. This helps stabilise your hips, easing lower back and pelvic pain.

6. Reduced herniated disc pain

If you have a herniated disc or rotate your spine, you may feel pain and pressure along your spinal nerves. A pillow between your legs can minimise the rotation of your spine, relieving your discomfort.

7. Relieved sciatica nerve pain

The sciatic nerve is the longest in the body and can cause pain down the back of your leg and lower back. Sleeping with a pillow between your legs can help maintain proper leg and pelvic alignment, reducing pressure on the nerve.

8. Decreased muscle stiffness

Sleeping with a pillow between your legs can maintain a supported posture at night, reducing soreness and preventing uneven muscle pressure. This can help you feel less stiff and more refreshed in the morning.

9. Reduced tossing and turning

Sleeping with a pillow between your legs can help stabilise your sleeping position, making it easier to stay comfortable and fall asleep. Combined with techniques for falling asleep quickly, this can lead to deeper, more restful, and uninterrupted sleep.

10. Added comfort and support

Placing a pillow between your legs adds a cosy, secure feeling that helps you unwind and drift off more easily. For some snoozers, it might just become your new favourite sleeping position.

Are there benefits to sleeping with a pillow under your knees?

Yes! If you prefer sleeping on your back, you may prefer having a pillow underneath your knees. It offers many of the same benefits, plus:

  • It keeps your back supported in a neutral position and supports the natural curve of your spine.
  • It helps to evenly distribute your weight, taking the stress off your spine.
  • It can reduce the likelihood of rolling over into a less comfortable position in the middle of the night.

Who should sleep with a pillow between their legs?

While everyone can benefit from using a knee pillow, certain people may find it especially useful:

  • Side sleepers – Sleeping with a pillow designed for side sleepers can keep your spine and hips aligned.
  • Pregnant women – A knee pillow can help you sleep more comfortably at night, easing pressure on the lower back and hips.
  • Individuals with back or hip pain – Sleeping with a knee pillow helps reduce strain, supports posture, and can alleviate back pain.

Pair your knee pillow with the right mattress for your sleeping position for the best results.

Behind the trend of knee pillows

Like many modern trends, the idea of sleeping with a pillow between the legs gained popularity on TikTok, with @jordan_the_stallion8 being one of the most popular creators to talk about the topic:

While some claims, such as gaining two inches in height, may be overly optimistic, many people have reported real benefits from trying this technique. And with so many people trying it out, it’s become a small sleep technique that many don’t go without.

However, Jordan isn’t the only one advocating for this technique on social media. Other TikTokers, such as @Stretch_pad, are showing their support for the pillow leg sleep life:

How to choose the right knee pillow

You can use your regular pillow (the one that you put under your head), but you can also find smaller pillows specifically for your knees or legs. Whatever pillow you choose, you’ll need to consider a few things:

  1. Firmness – Choose a firmer pillow for more support, or a softer one for added comfort.
  2. Shape – Contoured or memory foam knee pillows help maintain alignment while sleeping.
  3. Cooling features – Pillows may trap heat during the night. Look for a cooling option.
