The Knee Cube helps you get better sleep by alleviating pressure on your hips, knees, and ankles. It also helps your lower back stay aligned so you don't wake up in pain.  Unlike other leg pillows, the Knee Cube is designed to run the entire length of your legs, ensuring those sweaty flesh tubes don't touch during the night. Better yet, we've upgraded it with our premium temperature-regulating memory foam to keep everything nice and cool.
