What is the difference between a freestanding and an attached mobile pedestal?

Freestanding mobile pedestals are standalone units that can be moved independently — they roll anywhere under or beside a desk on their casters. Attached pedestals are connected to the desk frame with brackets or L-clips that keep them aligned with the desk but can still be separated. Some systems use 'semi-attached' designs: the pedestal slides onto a runner on the desk underframe but is not permanently fastened, allowing removal with one motion. For most applications, freestanding mobile pedestals are the most flexible choice. Attached configurations are preferred when aesthetics require the pedestal to appear integrated with the desk panel system.
