Yo-Yo Desk for adjustable heights (Rochester)

The fabulous yo-yo desk aid to adapt your existing table or desk into an adjustable height work zone! A great item for smaller work zones (and l believe quite popular).
It works by a manual lever and the counter weight inside (possibly pneumatic?) helps you manually lift up and down with relative ease with no electricity used (bonus).
White painted heavy metal adjustable post and weighted base, and white tough laminate (over MDF) finish upper moving base.
Was Freecycled and used by us and we have now replaced it for a larger whole moving desk.
Note some signs of use shown in the close-up photos but could be paint “touched up” or the plastic comes off and could be re-sprayed separately 🤔
Easy parking at the front door, no steps.
Item is heavy but manageable to a car.
Earliest collection is ideal :-)
