The lip of my shower is only 3″ high – it might as well be 3 feet when it is time to transfer. I can use gravity to slide back and forth between chair and shower seat, but gravity also keeps my feet planted on the floor. It’s even tougher getting into bed, when I need to drag my dead weight leg up onto the mattress.
This liner, the rubberized type, is light weight, strong, and won’t slip, either off my leg or out of my hands.
One roll can provide 3 or 4 straps. I keep one by the bed and another in the bathroom. The others are spares, because they will wear out after a year or so. I also use it to finish getting into bed. I simply loop it around my leg, just above the knee, and then pull my leg into bed.
