When someone requires assistance getting into and out of bed, it usually means that they have diminished strength. Adding a bed rail to the bed won't help if they are not strong enough to use it. The M-Rail is ergonomically designed to provide optimal hand positioning, making the task of getting out of bed easier and more comfortable. The unique contour and non-slip foam of the handrail reduces the chance of injury while promoting safety. The M-Rail's strong nylon webbing safety strap and foam mattress grips allow for secure support, and for protection from falling out of bed. Because the M-Rail requires no tools and is easily dismantled and portable, many choose to take their M-Rail with them from one place to another. The M-Rail will fit from single to king sized beds, and is an excellent choice for residential settings. Height 17" (43 cm). Width 18" (46 cm). Length under bed 38" (97 cm). Weight capacity 250 lb. (115kg).
