The client was looking for a workbench that had options galore. That included a bench that could easily be moved, overhang so that you could sit it comfortably and be a woodworking workbench as well.
We designed a bench that has an overhang and a lower shelf, allowing seating around the bench on stools. Retractable castors allows the person working on the bench to have an entirely stable work surface, something that we have found locking castors not to give. And it is a workbench as well.
This is a great bench to sit around and do your work if you are home schooling, although it is a little bit late now for lock-down schooling (we hope).
