I am more than happy to give a five star review for the Adjustable Bed Rail I recently purchased. My husband had begun to fall out of bed occasionally resulting in my having to call for help as I could not lift him up. The fact that it expands to fit the length of the bed and also drops down when he is going to bed and when he is getting up in the morning makes it absolutely invaluable. I simply couldn't manage without it, for me and for my husband the adjustable bed rail really is an essential aid.
