Yes, side or bed rails generally aid in preventing falls for those at risk of falling out of bed. Extendable bed rails allow users to adjust the rail to fit the length of their bed, which provides extra protection and peace of mind. When not sleeping, users can shorten the rail to serve as a supportive handle when maneuvering in and out of bed. It’s important to remember that for those with significant physical or mental limitations, bed rails should not be used as a substitute for vigilant nursing care.
