Most Comfortable Support: Our Jacobable body positioning cushion measures 20" x 9.8" x 6.1" and is ergonomically designed. It gives the body enough support, can be used for a long time, and is not easily deformed. The 30-degree incline is the most comfortable angle for your body, offering the best lateral sleeping position and allowing you to enjoy high-quality sleep with the offset pillow. Soft on the skin and non-slip: our lateral offset pillowcases are made of the most comfortable velvet with a unique embossed texture. The base is made of black fabric with antiskid points, and the pillow core is made of high-density foam which is compressed when you receive the package. Please allow a few days for it to return to perfect condition. Medical Wedge Pillow: The body positioning pillow is a great recovery partner and can be used in post-operative care. It helps patients turn over and provides better back support. Elevating the legs improves blood circulation in the legs and releases pressure on the back, lower back and legs. 【Pain Relief】It is often difficult to fall asleep when you are not feeling well, so a wedge pillow will make you feel better. It is easier to fall asleep on the side than on the back, making it a good companion for side sleepers. It relieves back pain, sciatica, prevents and treats pressure sores, and reduces pressure on the spine. Keeping the patient in a prone position prevents reflux. 【Easy to Clean】Our sleeping wedges are equipped with invisible zippers for easy cleaning. The pillowcase is removable and machine washable. It is not recommended to wash the pillow core. It is recommended to keep it in a ventilated place to keep it cool.
