Veridesk.com. Converts a normal desk to a standing desk. Designed to be used on a corner/L shaped desk but works on a regular desk when deep enough.
Worked to easily hold two monitors. Anyone can adjust it easily by gripped the two handles and pulling up or pushing down. Pictures show max height but can be adjusted to any range within the minimum and max.
Is relatively heavy making it very sturdy.
Top has a couple marks/scuffs but relatively unnoticeable. Had to get a smaller desk with a move and am no longer able to fit it.
Max height 18 inches
Max width 48 inches
Max depth 32 inches
