The traditional paper roll is simply laid loosely on top of the therapy bed, it isn’t secured to the therapy bed. As a result, in most cases it will fall off the bed when the client moves or turns over, exposing the shared surface of the therapy bed.The paper rolls are also quite noisy and uncomfortable for clients, and unrolling it to tear a new sheet can be awkward. Not only that, paper rolls that have a polyethylene backing cannot be recycled and those without the backing have limited bacterial filtering properties.
