Grow To Sleep's unique elasticized center provides flexible support to accommodate a growing belly, and there's less bulk in the center area so you stay cooler. The contoured ends and flexible design conform to your body's natural curves, and it's easy to position. Elevates and aligns hips to ensure neutral position and proper joint support. Remove ends to get two versatile body pillows, generously sized nursing pillows, or single belly support pillow. A must for moms-to-be carrying twins! Removable/washable cover.
