What to consider when purchasing a knee pillow

Here are some things to consider, so you get the right pillow for your needs.

Sleep position: Do you sleep on your side, your back, your stomach, or a combination? Different pillows are designed specifically for different sleep positions.

Size: Some pillows come in one size; some in multiple sizes. Especially if your height or weight is above or below average, you might want to consider a knee pillow with multiple sizes.

Material: This can apply to both cover and pillow base. Covers come in cotton, organic cotton, bamboo and other types of materials. The pillow base is generally made of memory foam, but you may find cotton batting, buckwheat, or other materials.


Any pillow between the knees can help alleviate pain. However, specially-designed knee pillows seem to do a better job. They support the body, allowing muscles to relax, so you stay asleep all throughout the night and rise pain-free.
