The only bed rail that adjusts in length after installation. Works well as a side rail to keep you from falling out of bed, as well as a support bar for getting in and out of bed. It adjusts from 26″ to 34″ to 42″ with the push of a button. The rail also folds down and out of the way when it isn’t in use. Can be installed on either side of the bed in between the mattress and box spring. Includes a dual safety strap that secures it to the bed frame. Works well on any size home or hospital bed rail and at 23″ high it accommodates the thicker pillow top mattresses. Excellent for seniors and anyone else who is need of home care. Cannot be used on UK profiling beds.
