What's the difference between Z-lift and parallel/straight-up converters?
Reviewer consensus
Z-lift designs (like the VariDesk Pro Plus) swing forward as they rise, eating desk depth but feeling very stable. Straight-up designs (like the VIVO V-series and most two-tier units) stay in the same footprint, which suits shallow desks but can show more side-to-side wobble at full height per specialist-community discussion.
