The 30 inch Safety Bed Rail from Stander prevents rolling and falling out of bed. This adult bed rail folds to the side of the bed making it easier to get in and out of bed. The 30 inch Safety Bed Rail is reversible and can be placed on either side of the bed. The guard rail sits is 23" high from the base of the mattress. The included safety strap runs underneath the mattress and buckles to the bed frame, preventing the rail from slipping or sliding. The 30 inch Safety Bed Rail can be easily assembled and installed on most traditional and platform bed types. It is designed to keep a low profile while matching the look and feel of your home.
