The FlexiSpot 40" Standing Desk Converter is a large-format sit-stand riser with a dual-tier design featuring a separate keyboard tray and a spacious main work surface. It uses a spring-assisted lift mechanism that raises 0–17 inches, accommodating most desk heights and user frames. The converter holds dual monitors (up to 35 lbs total) and sits atop your existing desk, making it ideal for home offices and shared workstations. Pre-assembled, tool-free setup. Wide 40" width suits multi-monitor setups and reduces the need to shuffle papers. FlexiSpot is an established ergonomics brand with strong community presence. Occasional reports of spring stiffness over heavy use; footprint is substantial (~26" deep when fully raised).
