10 Best Orthopedic Knee Pillows 2025 in the United States

The Contour Legacy Leg & Knee Foam Support Pillow is designed to provide relief from pain and discomfort in the back, hips, knees, and joints, especially for side sleepers. It's made from ventilated memory foam, which allows air to circulate and helps maintain a cool sleeping environment. This is beneficial if you tend to overheat during the night.

The pillow features an ergonomic, crescent shape that supports both legs and knees, helping to maintain proper alignment and reduce pressure points. This design is more versatile and comfortable than traditional knee pillows, which often require restrictive straps to stay in place. The memory foam is a good choice for those who need a firm yet comfortable support. Additionally, it has a washable cover, making it easy to keep clean.

However, it seems to come only in one size and color, which might not suit everyone’s preference or body type. The product also includes a 1-year manufacturer warranty, which provides some peace of mind in terms of durability and quality. While the lack of adjustability in terms of size or firmness might be a drawback for some, the design and features make it a strong option for those looking for specific pain relief and better sleeping posture.

The 5 STARS UNITED Knee Pillow is a soft memory foam pillow shaped like a wedge, designed mainly for side sleepers who need relief from hip, knee, or lower back pain, including sciatica sufferers and pregnant women. Its size (about 10" long by 8" wide and 6" high) fits comfortably between the knees to help keep your legs separated and your spine aligned while you sleep. This can ease pressure on joints and muscles, encouraging better rest.

The pillow’s standout feature is its cooling, breathable cover that keeps you comfortable through the night and is removable for easy washing. Although the foam core itself isn’t washable, the cover’s anti-pill material helps maintain hygiene. Unlike some similar pillows, this one does not come with a strap to hold it in place, which might be a drawback if you tend to move a lot during sleep. Still, many users find it stays put well thanks to its shape and firmness. The firmness is on the softer side, which is gentle on your knees but still supportive enough to prevent them from pressing together. Its certified safe memory foam means you can trust the materials used in terms of health and durability.

This pillow also offers flexibility in how you use it—not just between the knees but also under or between other parts of your legs for added comfort. It’s a solid option if you want a simple, effective orthopedic pillow to help reduce pain and improve sleep posture, especially if you prefer a softer feel and appreciate a cooling cover. However, if you need extra security to keep the pillow firmly in place, you might want to consider alternatives with straps.

The 5 STARS UNITED Knee Pillow is designed for back sleepers who need support to alleviate leg and lower back pain. Made from premium memory foam, it contours comfortably to your knees, legs, and thighs, enhancing spinal alignment and boosting blood flow.

This pillow is versatile and can be used under the knees, between the knees, under the ankles, or along the upper leg, making it suitable for side and back sleepers, pregnant women, and those recovering from surgery or injuries. The pillow measures 20.4” x 7.8” x 4.8”, providing custom support, and comes with a cooling, breathable, and machine-washable cover, which is perfect for hot sleepers and summer months.

The foam core is not washable, which might require careful maintenance to keep it hygienic. The pillow's firmness is balanced for comfort, but those needing extra firmness may find it less supportive. Certified by OEKO-TEX and CertiPUR, it ensures safety and sustainability. Weighing 1.69 pounds, it is lightweight and easy to handle. While it is a great choice for those needing ergonomic support, some may need a firmer option depending on personal preferences.
