Progressive Automations Standing Desk Corner Frame FLT-05 Triple Motor (Grey)

Pros

  • +Three legs and triple motors lift a 90-degree corner rated to 330 lb
  • +Collision detection with 11, 22 and 33 lb sensitivity settings
  • +96-month warranty, second only to UPLIFT in this roster
  • +Installs in a left-hand or right-hand corner orientation
  • +Matched primary and secondary tops are sold for the frame

Cons

  • The most expensive frame here before you source a corner desktop
  • A two-arm L-shaped top is the hardest DIY surface to fabricate
  • The 42.7-72.6 in span describes the frame, not each arm of the L
  • A corner frame commits your room layout in a way a rectangle does not
