The Best Knee Pillows for Side Sleepers

Woman, sleeping on her side

A good quality knee pillow can make a huge difference to your sleeping habits if you’re a side sleeper. Here’s a look at some of the best knee pillows out there.

A knee pillow means your knees are supported when you sleep on your side, but it also means that your back and hips are given some relief too. If you have any issues with any joints, such a pillow can make a big difference in how your body rests at night. In particular, they’re great for relieving sciatica pain and pressure on your lower back.

Not all knee pillows are the same though, so we’ve focused on a few specific areas so that there’s a knee pillow for your situation. After all, it’s important that you’re comfortable while you rest, otherwise, the quality of your sleep can be negatively impacted.

A contoured pillow means you get all the support in all the right places. The ComfiLife Orthopedic Knee Pillow is the best of the bunch. It’s made from 100% premium quality durable cut memory foam so it feels comfy for your knees and provides the exact level of support you require. That level of support means that your knees, back, and hips are all appropriately supported throughout the night.

The pillow is designed in an ergonomic manner so that your legs, hips, and spine are kept in ideal alignment while you sleep, so there’s no fear of cramping, aches, or poor circulation. In terms of cleaning, it has a breathable cover that’s removable so you can easily machine wash it on a regular basis.

If you’re liable to move around a lot in your sleep, it can be useful to have a knee pillow that also has a strap to keep it firmly attached to your body. The Everlasting Comfort 100% Pure Memory Foam Knee Pillow with Adjustable & Removable Strap and Ear Plugs is the best of the bunch here. Like the ComfiLife, it’s made from 100% pure memory foam and contoured in a way that means it fits perfectly between your knees. That means just the right level of support for your legs, hips, and spine.

Where this pillow differs is with the all-important removable strap. It uses a hook-and-loop strap so it’s easily adjustable. Using it means your knees can be kept in perfect alignment even if you roll over a lot in your sleep. Currently, you also get a free pair of earplugs to help you sleep even better.
