There are some soft hot tub covers that have child proof straps that hold it into position and are made of tough material that is unlikely to tear if a child inadvertently walks across it. However, soft hot tub covers are not as stable as the hard hot tub covers that are designed to allow individuals to sit or walk across them if needed. Soft hot tub covers are not the best choice for individuals who have large pets that may walk across it or children that might happen to walk across it.
