This section features bed rails and bars to help people get in and out of bed easily. These items can be an important means of support for people with limited balance or strength. Disability bed rails can also help prevent the user rolling out of bed at night. A bed rail for an elderly person can be an important safety feature. Many of the rails are adjustable both in length and height. Some are suitable for slatted beds, while others fit divans. A bed grab rail may clamp or strap to the bed frame itself, or fix by having a section which slides beneath the mattress.
