Selling for only $25 because the pulley system in the central column is broken and it is stuck at the extended level. I'm 5'9" and it fits me perfectly. If you just need a standing desk this is a heavy-duty, commercial-grade table converter Model: 33-349-200. Unlike cheap tabletop risers that wobble when you type, this clamps securely to the front of your desk. Or perhaps you can fix it or use it for parts. No haggling over price, no trying it out, and I don't deliver. New models cost close to $1000.
