Dual Wedge Design: Unlike ordinary leg pillows, our innovative double wedge design elevates both legs simultaneously. This ergonomic approach alleviates pressure on your lower back, hips, and knees, relieving sciatica, arthritis pain, ensuring ideal spinal alignment. Wider and longer, the extra big size makes the leg pillow perfect for people taller than 5'7". Helps after surgery recovery. Premium Memory Foam: Crafted from high-density, body-conforming memory foam, passed SGS test certified foam, this pillow conforms to your legs' unique contours. It evenly distributes your body weight, eliminates pressure points, and allows your muscles to relax fully.
