10 Best Knee Pillows 2025 in the United States

The Contour Legacy Leg & Knee Foam Support Pillow is designed especially for side sleepers who experience discomfort in their back, hips, knees, or legs during sleep. Made with ventilated memory foam, this pillow offers good firmness and support, helping to keep your legs and knees properly aligned to reduce pressure and pain. The ventilation holes in the foam help keep the pillow cool throughout the night, which is a nice feature if you tend to overheat under regular memory foam.

The crescent-shaped ergonomic design fits comfortably between your legs without needing straps, allowing easy movement during sleep. It comes as a two-pack, sized about 10 by 9 inches each, so you get plenty of cushion for both legs. The covers are made from polyester and lyocell, materials that feel soft and are machine washable, making it easy to keep clean.

A minor downside is that the pillow is somewhat lightweight (7 ounces), which some people might find less stable if they move a lot in bed. Also, while the firmness is generally supportive, it might feel too soft for those who prefer very firm cushions. This pillow is a strong choice for adults seeking relief from joint or nerve pain caused by poor sleeping posture, especially side sleepers looking for an easy-to-use, breathable leg support.

The Contour Legacy Cool Leg & Knee Foam Support Pillow is designed especially for side sleepers who need extra support for their knees, hips, and lower back. Made from soft gel memory foam, it offers gentle cushioning that helps align your legs and pelvis, reducing pressure and discomfort caused by bone-on-bone contact. Its ergonomic wedge shape with tapered edges allows you to move naturally throughout the night without feeling restricted.

This two-pack provides a larger size pillow that supports both thighs and knees, which can be great if you prefer more coverage or want one for travel and one for home. The pillows come with removable, machine-washable covers, making them easy to keep fresh and clean. One of the highlights is the cooling gel foam, which helps prevent heat buildup, a common problem with many foam pillows.

On the downside, the pillows are on the softer side, which might not provide enough firmness for those needing firmer support or with heavier legs. Also, while the wedge shape is good for alignment, it might take some time to get used to if you’ve never used a knee pillow before. For those looking for comfortable, cooling, and easy-to-maintain leg support, especially as a side sleeper dealing with joint or nerve discomfort, this pillow set is a solid choice.

The cover is soft, breathable, and anti-pill, enhancing comfort while being easy to maintain, as it is removable and machine-washable. However, the foam itself should not be washed, which could be seen as a minor inconvenience for some users. The firmness is described as soft, which might not be ideal for those needing firmer support. The product is certified by OEKO-TEX STANDARD 100 and CertiPUR, ensuring it is a safe and sustainable choice. It is also HSA and FSA-approved, adding to its credibility.
