These are amazing! I am an administrator at a school and I ordered two of these, one for myself and one for my assistant principal. We are able to easily move through the school with our computers and needed resources stored on the cart to help in classrooms. I use mine every morning so that I can stand and work at my computer in the hallway while also welcoming students as they arrive. ￼￼ The surface easily adjust from standing to seated height as well as tilted to flat. I love, love, love them! I even went back and ordered a third for my father who is disabled and spends most of his day in his chair, this gives him a sturdy work or eating surface with storage and it can easily be rolled out of the way￼￼! Yes, I have purchased three of them now and have told everyone I know about them. A few of my teachers are ordering them for their classrooms next year! ￼
