10 Best Under The Knee Pillow 2025 in the United States

The 5 STARS UNITED Knee Pillow is designed to help side sleepers, pregnant women, and anyone with hip, knee, or lower back pain find relief during sleep. Made from soft memory foam, it offers gentle but supportive cushioning that contours to your legs for comfort. Its wedge shape and size (about 10" long, 8" wide, and 6" high) make it versatile enough to be positioned between knees, under legs, or calves to improve spinal alignment and reduce pressure.

The pillow's cooling, breathable cover is removable and machine washable, which helps keep it fresh and comfortable throughout the night. Although it does not have an adjustable firmness setting or a strap to keep it in place, users have found that its ergonomic design stays put well for most sleeping positions. This pillow works best for adults looking for a soft, easy-to-use solution for joint and back pain, especially if you prefer a straightforward design without extra features. However, if you need a firmer cushion or more customization options, this might feel a bit too soft.

The product's certifications ensure it’s made with safe, quality materials, making it a dependable choice for regular use. In short, it’s a solid option for anyone seeking gentle support and pain relief without complexity.

The Contour Legacy Plus Leg & Knee Pillow is designed mainly for side sleepers who need extra support to ease pressure on their hips, knees, and lower back. It uses high-density charcoal-infused memory foam, which molds to your leg shape while staying firm enough to maintain proper spinal alignment. This makes it a good choice if you’re dealing with pain from conditions like sciatica or hip discomfort.

The wedge shape fits naturally between your legs, helping keep them in the right position to improve circulation and reduce joint strain during sleep. A notable feature is its breathable, ventilated design that helps keep you cool all night, which is great if you tend to get warm under heavier pillows. The removable cover adds convenience for cleaning, which is always a plus.

On the downside, the pillow is a single size and wedge-shaped, so if you prefer a different size or more adjustability in thickness or firmness, this might not be ideal. Also, its firmness is medium to firm, which won’t suit those looking for a very soft cushion. This pillow suits adults who sleep on their side and want targeted leg support to relieve pressure and improve comfort during the night.

The Contour Legacy Leg & Knee Foam Support Pillow is designed to help reduce discomfort in various areas such as the back, hips, knees, and sciatica nerves, making it a good choice for side sleepers. Made from memory foam, it contours to the shape of your legs without needing restrictive straps, allowing you to move freely during the night. Its ventilated design helps regulate temperature, preventing overheating for a cooler sleep experience.

The memory foam, combined with a cotton cover, provides a soft and comfortable texture, although some users might find it too soft depending on their personal preference for firmness. The pillow's size and shape are designed to support both legs and knees, contributing to better sleeping alignment and reduced pressure points. It's also washable, which adds to its convenience. However, at just 7 ounces, some users might find it lighter than expected.

The product comes with a 1-year customer care warranty, which offers some peace of mind. While it may not suit everyone's firmness preferences, it's a popular choice for those seeking relief from sleeping discomfort.
