Leachco's Swankle is an elevated wedge pillow for swollen ankles. This is one of the many battles that pregnant women often face. We know the best method of combat is to elevate the end of your mattress, keeping your swollen feet elevated throughout the night. That's why we created the Swankle Elevated Wedge Pillow. Not only does it provide adjustable elevation for swollen ankles or restless leg relief, but the Swankle can also be used at the head end of your mattress to combat reflux or used separately as a support wedge with a variety of targeted support options to meet your needs. Removable zip-off cover is machine washable and dryer safe and made of 65% polyester and 35% cotton. Made in the U.S.A. To help relieve swollen ankles or promote restless leg relief with the Swankle Elevated Wedge Pillow, place it between your box spring and mattress at the foot end of your bed and simply pull out or push in with the convenient carry handle to adjust elevation as needed. For upper body elevation, which is a must for reflux or better breathing, place the Swankle at the head end of your bed in the same manner. Used separately, Swankle makes a great targeted relief pillow. For doctor recommended side sleeping, place Swankle in front to support your growing tummy or behind you to soothe an aching back. Use for adjustable upper or lower body elevation any time, anywhere you need it. You can even use Swankle as a back rest while lounging; place large end of wedge down or up to promote better posture while providing support.
