Here are some steps you can take to reduce the risk of bed rail entrapment: Measure the mattress’s thickness and buy a bed rail recommended for that measurement. Ensure the mattress is firm and the bed rail fits tightly against it. Pull the anchor strap as tight as possible to get a snug fit. Learn about entrapment zones so you install the bed rail a safe distance from the headboard and footboard. This information may be in the owner’s manual. Buy a bed rail with a bumper or purchase one separately. Most mesh bumpers double as organizational pockets. Add a bed rail mattress safety guard. Consider an alternative to bed rails, such as foam bumpers that strap to the mattress. Overhead pull straps can also assist with bed transitions. Consider movement alarms if there’s a chance your loved one will get confused and fall or climb out of bed, regardless of the rails or bumpers you install.
