I made this kids workbench as a Christmas present for me niece. I found the plans for it here: fixthisbuildthat.com/diy-kids-workbench-plans/
The bench is 24″ high at the work surface, 17 1/2″ deep and 41 3/4″ tall. It is made out of select pine 1×4 and 2×2 boards with an MDF top, shelf and pegboard. The joinery is all done with pocket screws. The finish is tung oil.
