We have a cemented floor crawl space under the main part of our house & I use it for storage of seasonal and seldom used things. But crawling around or trying to walk bent over, was getting difficult. This is perfect. Still have to watch our heads under some of the pipes and ducts, but so much better for us old folk. It wasn't too hard to assemble, and my 240 pound spouse fits on it and scoots around to find things and spray for bugs and spiders. He likes that it has storage for things he needs like spray cans, a small whisk broom rags, etc.
