ContourContour Legacy Leg & Knee Foam Support Pillow for Side Sleepers Soothing Relief for Back, HIPS, Knees, Joints, Nerves & Muscles (2 Pack, Ventilated Memory Foam)
Main highlights- VENTILATED MEMORY FOAM ALLOWS AIR TO CIRCULATE FOR A COOLER NIGHTS SLEEP – Unlike traditional memory foam leg pillow that are designed to absorb your body heat in order to compress, the Contour Legacy Leg Pillow is designed with ventilated air holes in the memory foam that promote air circulation throughout the night. The temperature regulating foam technology pushes the heat outwards away from your body, to prevent you from feeling like you are overheating.
- THE ONLY LEG PILLOW THAT SUPPORTS BOTH YOUR LEGS & KNEES – When we first invented our leg pillow back in the early 90’s (the hour glass shape that so many companies have now copied), our goal was to improve sleeping alignment to reduce pain. The leg pillow was invented to help reduce pressure that occurs from bad sleeping posture which causes discomfort. Years later we realized that cushioning & supporting BOTH your legs & knees are important in maintaining proper alignment to help reduce pain.
- SLEEP COMFORTABLY IN ANY POSITION & MOVE FREELY THROUGH THE NIGHT – Unlike traditional knee pillows, the Contour Legacy features a true ergonomic design with its soft curves & crescent shape to fit men & women comfortably. Without requiring hazardous, circulation restricting straps, the precise tether of the pillow contours to fit the natural shape of your legs. This allows the foam leg pillow to contour to your shape without restricting movement or requiring you to sleep in a certain position.
- ORTHOPEDIC LEG PILLOW TO HELP REDUCE BACK, HIP, LEG, KNEE & SCIATICA NERVE DISCOMFORT- As a side sleeper, you don’t sleep perfectly straight. Your top leg drops in front of you putting pressure on your back, your hip joints twist & your knees touch, causing pain. The Contour Legacy Pillow is the best leg pillow cushion for those looking for relief as the cushion comfortably supports your legs & knees to provide proper sleeping alignment & positioning to eliminate those painful pressure points.
