This Dual Motor Electric Standing Desk with 55' Tabletop from Mount-It! uses a black steel and aluminum frame to support a 55' white top. The 29.3 to 48.2' height range can be adjusted using the touch control panel. Save up to three different heights so you can have consistent settings to return to when you need the desk to adapt to your ergonomic needs. The dual-motor design is powerful and raises the tabletop at a consistent 1 inch/s while staying under 50 db in sound. This desk can support up to 220 lb so you can raise and lower your whole setup.
