Roll out a just-right-height temporary table
It's always a time-consuming exercise to get a support table to match the height of my workstation when I need extra space. A single roller stand fulfills the height adjustability requirement, but it tends to be unstable for stationary work. But two roller stands, and a plywood tabletop with channels to fit over the rollers, provides just the right solution. Build the top as shown, and you have a temporary adjustable-height table anytime you need the extra workspace.
