Your upper leg falls in front of you, exerting pressure on your back, twisting your hip joint and touching your knee, causing pain. Legacy pillows are the best leg pillows for those seeking relief, because the pillows comfortably support your legs and knees, providing correct sleep alignment and positioning to eliminate those painful stress points. 2. The only leg pillow that can support both legs and knees - the invention of leg pillow is to help reduce the pressure caused by bad sleeping posture, which will cause discomfort. After a few years, we realized that the cushioning and support of legs and knees are very important for maintaining correct alignment to help alleviate pain 3.
