I am tall so I use my Vertdesk at its maximum height. I am so pleased how sturdy and stable it is, and using it is a total pleasure. The desktop surface material feels harder and more solid than I expected from a composite. I have one suggestion for anyone considering these desks. The paper assembly instructions are good, but I strongly urge you to first watch the excellent 15-minute YouTube video where the BTOD founder assembles the desk, going through the instructions step by step - I had much more confidence that I could assemble mine without errors after watching the video.
