What are the advantages of a freestanding monitor arm base vs. a desk-mounted arm?

Freestanding monitor arm bases (a weighted base that sits on the desk surface or floor) offer: (1) No desk modification — no clamp or grommet hole required, ideal for shared or rented desks; (2) Easy relocation — the entire arm moves by picking up the base; (3) Compatibility with glass or non-standard desks; (4) Ability to position the monitor anywhere within the base's weight-balanced footprint, not constrained to desk-edge positions. The trade-off: freestanding bases occupy desk surface area (typically 8"–12" × 8"–12"), somewhat negating the desk-clearing benefit of a monitor arm. For desk-mounted arms, the clamp or grommet mount keeps the entire desk surface clear. OfficeFurniture2go.com carries both desk-mounted and freestanding monitor arm options — call 1-800-460-0858.
