Sit-Stand Desk Converter with Keyboard Tray

Two-tier sit-stand desk converter in black, compatible with most standard desks. Upper surface accommodates one or two monitors, with a lower ergonomic keyboard tray on a separate level. X-frame scissor lift mechanism adjusts to multiple heights. Squeeze handles on the sides control the lift. Gently used and in good working condition. Moves up and down very easily; does not require a lot of force. A practical upgrade for anyone looking to alternate between sitting and standing without replacing their existing desk.
