Yes, a bed scrunchie can work on an adjustable bed. There are a few things to keep in mind when using a bed scrunchie on an adjustable bed, though. First, make sure that the fabric of the scrunchie is compatible with the fabric of the adjustable bed. Second, be careful not to overtighten the scrunchie, as this could damage the adjustable bed. Lastly, make sure to remove the scrunchie before adjusting the position of the adjustable bed, as it could get caught and cause damage.
