This spill proof sheet creates an inflated border that keeps your bed mess free! The border inflates up to 5.5 inches tall, so you can get slippery, wet, and wild. The soft and slick material is durable, easy to clean, and simple to maintain. Just blow it up and fill it up with a bottle of Nuru Gel, or any liquid you please! The vinyl material is lightweight but strong, and is a great way to get truly dirty. Measurements: 78.5 x 67 x 5.5 Material: Vinyl Color: Black Note: Nuru gel and all accessories sold separately
