This client's daughter sleeps in a bed with rails at home however those are too big and cumbersome to travel with. This makes finding a safe way for her to sleep more difficult when not at home. Some travel rails exist but they are typically only for younger toddlers.

Your task is to design some simple safety rails that are lightweight and portable. They must perform as normal safety rails to prevent falling off the bed while not causing any injuries to the sleeper if there are any accidental bumps. It must be secure but easy to install and remove for travel. It should be adaptable to be installed on different types of beds. The surfaces and any fabric should be easy to clean and breathable.
