Do mobile pedestals tip over if you pull open a drawer with a lot of files in it?

A quality commercial pedestal prevents exactly that with an anti-tip interlock — a mechanism that physically stops a second drawer from opening when one is already out. This keeps the unit from going forward when a heavy file drawer is extended. It's a standard feature on BIFMA-compliant pedestals and a non-negotiable for file-heavy setups. FindOfficeFurniture.com includes anti-tip interlocks on all commercial pedestals — call 888-719-4960 if you need certification paperwork.
