- 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.
- 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.
- 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.
- 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 KNEE PILLOW FOR SIDE SLEEPERS - RELIEVES PRESSURE & PROMOTES ALIGNMENT: Sleeping on your side can cause your top leg to pull downward, twisting your hips and pressing your knees together. This leg pillow for side sleeping is designed to keep your spine, hips, and legs in alignment, helping reduce strain, pressure, and discomfort in your lower body. Use nightly as a sciatica pain relief pillow, hip pillow, or knee wedge pillow between legs to support natural rest for sore muscles
- SUPPORTS BOTH LEGS, KNEES & HIPS FOR COMFORTABLE SLEEP: Unlike small cushions that shift, our leg pillow is engineered with a dual concave design that cradles both knees and legs for stability throughout the night.

Unlike ordinary pillows that flatten, this durable memory foam knee pillow holds its shape night after night, ensuring consistent relief and lasting comfort for all body types. A great gift for any side sleeper who wakes up often
- ERGONOMIC CURVED SHAPE WITH ADJUSTABLE STRAP: Designed for side sleepers, the crescent curve and adjustable strap keep the alignment pillow between your legs while sleeping, even if you toss and turn. This helps maintain a smooth spine alignment without slipping or shifting out of place. Use it as a leg pillow for back pain, hip pillow for side sleepers, or a contour knee wedge pillow for pressure relief. Suitable for men, women, and recovery support after replacement surgery or injury
- REMOVABLE WASHABLE COVER & MULTI-USE SUPPORT: The breathable cover is removable and machine washable for fresh use every night.
