When you're expecting you may notice you need as much support for your growing belly as you do your back. The Back 'N Belly® provides equal support for back and belly at the same time. There's no need to reposition pillows during the night, simply turn from side to side. The inner contours were designed to follow the natural curved shape of your body. Features a comfort neck curve for neck and shoulders, and a zippered removable cover for ease of use. We have five styles of cover fabrics to choose from: Chic (fashion print in 65% polyester 35% cotton), Jersey (t-shirt soft jersey in 100% cotton or cotton/ polyester-blend), Plush (100% luxurious plush polyester), Organic (100% organic cotton), Supreme (100% cotton, 300 thread count).
