What's the difference between good and bad drawer slides on a mobile pedestal?

Commercial-grade pedestals use ball-bearing full-extension slides rated for 50–100 lbs — the 'full extension' part means the drawer pulls all the way out so you can reach the back. Budget units use partial-extension slides that leave the rear third of the drawer blocked. For file drawers, full-extension slides rated at least 50 lbs are essential to handle hanging file loads without drooping.
