How to Choose a Knee Pillow
The ideal knee pillow for your needs will often depend on the issue you’re trying to address. People with painful joints may prefer an option that can be repositioned into any area based on discomfort. Those who move around during the night often opt for a solution with an included strap to keep the item in place.
Here are some points you may want to consider when making the perfect choice.
Materials
The construction of your knee pillow will significantly affect how it feels in use. The most common material for these products is usually high-density memory foam, which can contour to your body while also bouncing back into shape when necessary. Some options come pre-ventilated to assist with airflow and breathability.
Many items also include a removable and washable cover to protect the internal filling and deliver an additional comfort level. Depending on your preferences, these cases can be hypoallergenic, sweat-reducing, and eco-friendly.
Ease of Use
Most knee pillows come carefully contoured to ensure they can fit naturally between your legs with minimal effort. Some can be placed in different positions around the body, giving you more freedom to eliminate common joint and muscle pains.
An included strap can be useful for keeping your wedge in place when you’re moving throughout the night. It’s also worth looking for a removable cover for easy washing.
Durability
The foam included in a knee pillow should be strong enough to withstand regular use and all kinds of body shapes or weights. Stronger products will bounce back into shape immediately after being compressed to provide a higher level of support.
If your item comes with a cover, it’s important to ensure the seams are well-made and the material isn’t prone to ripping or damage.
Summary
Our top pick from this list is The Slumbar Pillow Washable memory foam knee pillow. Ideal for eliminating a range of different joint and muscle pains, this product fits perfectly between your thighs with a contoured design. The foam filling is resilient against pressure and bounces back into shape after each use. Moreover, there’s an included washable cover, so you can refresh the scent of your purchase between bedtimes.
