BED RAIL and FITTED BED SHEET combined. Kids, Toddler, Children and Adult; TWIN (39in x 75in x 09in), White BED RAIL and FITTED BED SHEET, combined in one product. Prevents kids from rolling off the bed, in their sleep and fall to the floor. KID'S SAFETY product. Patent Pending. Unique, non Intrusive design. In our product, a child CANNOT slide under the bolster and fall off the bed, because the sleeve containing the bolster/insert is sewn to the fitted bed sheet. The KidsDontRoll System is a new product, intended to prevent children from unintentionally rolling off their beds while sleeping. Parents have traditionally placed pillows on the edge of the bed for this purpose, but there are inherent problems. Our product has long pillowcase like sleeves sewn onto the top surface of fitted bed sheet. Inserts can be inserted into the sleeves or taken out by parents as desired. Our new Patent Pending Design uses SOFT components (cloth & foam). When using the KidsDontRoll System, if your child were to kick in his/her sleep, he/she will be kicking aginst soft materials (cloth & foam) so it won't hurt. Since the sleeve containg the bolster/insert is sewn onto the fitted sheet, it stays in place. Systems, based on older designs, generally use hard materials like WOOD, METAL, etc. The design of the The KidsDontRoll System is so User Friendly, that even some 5 year olds can install / uninstall the product. In most other systems on the market, which are based on older designs, a parent has to get the child out or uninstall or fold it away. The KidsDontRoll System is designed such that AFTER the child wakes up, the system allows him/her to get out of their KidsDontRoll bed on their own. This feature is especially handy on weekends, if the parents want to sleep a bit longer.
