Knee pillows have for long been used to alleviate spine, hip bone, and knee, leg, and ankle pains. These sufferings may be as a result of surgery, injury, or during and after pregnancy. Poor sleeping habits may also contribute to these nagging conditions.

These knee wedge pillows help by aligning your legs and hip to your spine. They also offer a form of cushioning and massaging to the affected areas thereby leading to faster recovery.

What matters most when buying these pillows is the construction material which dictates how thick, firm, or soft the knee support will be. Ideally, opt for pillows cut from high-grade memory foam. Its thickness, however, depends on the amount of support you require. All in all, it shouldn’t be either too firm or rigid or too soft so that your knees touch each other.

Again, going for a hypoallergenic knee pillow is favorable since it does not harbor allergy-causing agents. Lastly, go for a pillow with a removable cover for easy cleaning.
