Keep your child safe from rolling off the bed with the Shrunks Bed Bolster. Inflates (to 48" long, 7" high and 4" wide) and slips conveniently under the fitted sheet of a standard size twin, queen or king size bed. The design creates the required barrier to prevent "roll-offs" but still allows room for parent or guardian to sit or lay next to the child for story time. When finished, simply deflate and fold up for compact storage. Cleans with mild soap and water. Product is free of phthalates, lead and BPA. Includes manual pump and repair kit.
