The 5 Best Knee Pillows Reviewed
Side sleepers often have it rough.
With all their body weight falling on their hips and shoulders, it can lead to restless nights and uncomfortable mornings.
It is possible to reduce the discomfort associated with side sleeping by adjusting one’s posture, mattress, or arm positioning.
However, even with all these adjustments, it can still lead to hip pain and nerve pain if you sleep on your side continuously for years.
It’s also possible to remove these factors of pain and discomfort simply by switching sleeping positions.
Sleeping on the back, for example, allows for body weight to be distributed much more evenly throughout the bones, joints, and muscles.

What To Look For In A Knee Pillow
There are a few major factors to consider when shopping for a knee pillow sleeping. You want something that will lift your upper leg, provide comfort to your bottom leg, relieve any pinched nerves, and realign the spine into proper position.
For all these things, consider:
- Support – The knee pillow needs to provide firm support to the leg it lifts up in order to provide relief to the lower one.
- Comfort – The rubbing together of bones is what causes discomfort, so it must be soft and comfortable. You’ll be spending several hours a night with it, after all. This aspect of comfort is especially important if you happen to suffer to one of the following ailments:
- Knee arthritis
- Spinal misalignment
- Hip Bursitis
- Recent surgery
- Bad backs
- Cooling – A thick buffer of cushion between your knees can be soft and cozy, but it becomes uncomfortable when that cushion makes you hot and sweaty. Some may offer cooling elements to help the sleeper remain fresh during the night.
Benefits of Knee Pillows
A knee pillow is beneficial in many more ways than one. It can play many roles, depending on the needs of the user. Some of the top benefits include:
- Pressure elimination – Reduced pressure on the knees, thus reducing hip and lower back tension as well
- Prevents hip rotation – Keeps your hips properly aligned
- Posture improvement – Allows your body to maintain proper posture while sleeping
- Improved blood flow – By elevating your leg, it allows for proper blood flow throughout the whole body
- Pregnancy comfort – During what can often be a time of interrupted sleep and discomfort in bed, a knee pillow can provide great relief for pregnant women
- Surgery aftercare – For some procedures, a knee pillow will provide comfortable sleeping postures after the fact, while the patient fully recovers
