10 Best Knee Pillows 2025 in the United States

The Contour Legacy Plus Leg & Knee Pillow is designed specifically for side sleepers who need better spinal alignment and pressure relief during sleep. Its wedge shape fits naturally between the legs, helping to ease hip, knee, and lower back discomfort. Made from high-density memory foam infused with charcoal, the pillow molds comfortably to your body while resisting flattening over time, which supports lasting comfort. The memory foam also includes ventilation features to keep the pillow cool throughout the night, preventing overheating—a common issue with many foam pillows.

The pillow is lightweight and comes with a removable cover, making it easier to keep clean, which adds to its convenience. However, the firmness level, while supportive, might feel too firm for those who prefer a softer cushion between their legs. The size is compact and suitable for most adults, but if you prefer a larger or more cushioned pillow, this one might feel a bit small.

This pillow represents a strong choice for anyone struggling with pain from side sleeping, such as sciatica or hip issues, but those sensitive to firmer materials might want to test it out before committing.

The Contour Legacy Leg & Knee Foam Support Pillow is designed with side sleepers in mind, offering relief for issues like sciatica and knee pain. One of its primary strengths is the ergonomic hourglass shape, which helps maintain proper alignment while sleeping. This design effectively supports both legs and knees, reducing pressure points that can cause discomfort during the night. Additionally, the ventilated memory foam is a standout feature as it allows for better air circulation, keeping the pillow cooler and more comfortable than traditional memory foam options.

On the downside, while the soft firmness is beneficial for comfort, it may not provide enough support for everyone, especially those with heavier body types or specific orthopedic needs. The pillow's dimensions (10"L x 9.5"W) may also feel a bit small for some users, limiting its effectiveness if you need more extensive support. Moreover, it is marketed as being suitable for any sleeping position, but some users might find the design is best suited for those who primarily sleep on their sides.

The pillow cover is washable, which is a plus for maintaining hygiene, but it could be a bit tricky to remove and put back on due to its snug fit. Lastly, the product comes with a one-year warranty, which offers some reassurance about its quality. This pillow is a solid choice for side sleepers seeking relief from discomfort in their legs and hips, particularly if temperature regulation is important to them. However, potential buyers should consider their specific support needs and sleeping positions before making a purchase.

The 5 STARS UNITED Knee Pillow for Side Sleepers is designed with key features that make it a suitable choice for those experiencing hip and back pain, as well as side sleepers and pregnant women.

It is lightweight at just 13.7 ounces, making it portable and easy to handle. 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.
