The Avana 4-in-1 Flip Pillow Convertible Bed Wedge is a multi-functional bedding product that transforms to suit your needs by offering ergonomic lift and support in a variety of sitting and laying positions. Sit it upright and lean it against your headboard for extra lumbar support while reading in bed. When the lying flat, there are two configurations: choose either a steep or gentle slope to relieve pressure and provide support to your knees and legs. Finally, place it under your head for a slight lift when resting. The antimicrobial Bamboo cover is both removable and machine washable.
