Yes, it is safe, because it basically rely on gravity to do the pull. Just go read those reviews on Amazon to get an idea of how it can help pick the one you like. You will see most reviewers are people who have back problems.

Personally, I have one that helps my neck pain. I don't have lower back pain. But it is supposed to help all spine problems. Good luck.
