Best Knee Pillows of 2022

Sleeping with a pillow between your knees supports optimal spine alignment. Particularly if you’re a side sleeper, this simple adjustment can help relieve joint and back pain. Knee pillows are simply orthopedic pillows designed specifically for this purpose – they are shaped to match the natural contours of your body and made from supportive materials like memory foam.

While it may seem like one knee pillow is like any other, there are some important features to consider. We’ve done the research and testing to bring you our top picks for the best knee pillows on the market.

Knee Pillow Reviews

Knee pillows are extremely popular among side sleepers but, really, they are a great option for anyone who suffers from chronic back pain or joint pain. There are many different knee pillows to choose from, but we’ve done the hard work for you in narrowing down the options to our top 5 picks.

FAQ

Q. Do knee pillows help with knee pain? A. While a knee pillow probably won’t cure the cause of your knee pain, it can provide temporary relief while you sleep. If you sleep on your side and you wake up with sore knees because they rub together during the night, a knee pillow could help.
Q. Is it good to sleep with a pillow between your knees? A. Yes, depending on your sleeping position. If you are a side sleeper, putting a pillow between your knees keeps your hips from sinking and supports the proper alignment of your spine.
Q. Where do you place a knee pillow? A. It depends on your preferred sleeping position. If you are a side sleeper, place the pillow between your knees so your hips are square and your spine properly aligned. If you are a back sleeper, place the pillow on the mattress with the backs of your knees resting on the pillow.
Q. Why does putting a pillow between your legs feel good? A. Certain sleeping positions tend to put excess pressure on different parts of the body. As a side sleeper, you’re most likely to feel pressure on the shoulders and hips, though you may also wake with back pain. As a back sleeper, you may feel extra pressure on the lower spine. Placing a pillow between or under your legs can help relieve some of that pressure and keep the spine in proper alignment.
Q. How thick should a knee pillow be? A. The ideal thickness for a knee pillow is somewhere between 4 and 6 inches. It should be just thick enough to keep your knees the right distance apart that your spine is properly aligned.
