Yes it does twist. It is very tight when you first get it. You can lefty-loosy or righty-tighty it. Loose means the chair will tilt backwards easier. If you tighten it all the way it will be next to impossible to tilt backwards. If you make it too loose you could tip back too easily, BUT you have to crank and crank it to get it to be too loose. So cranky away, test it, then crank again until you like it.
