We really don't understand why someone's back would experience any more discomfort
working with the MaxJax on a rolling seat than standing erect on hard concrete. What's the difference? Working with the MaxJax does not contort your neck, but working on cars that are elevated above you sure does. Think about how nice it would be to sit down on a padded seat for some of those tedious under-car jobs. Our customers swear they prefer working with the MaxJax over standing all day on a hard concrete floor. Try it out, you probably will too.
