Step-by-Step Assembly
- Assemble the Main Frame: Attach the horizontal support bars to the vertical leg frames using the provided screws. Ensure all connections are secure but do not fully tighten yet.
- Attach the Desktop: Carefully place the main desktop panel onto the assembled frame. Align the pre-drilled holes and secure the desktop to the frame using the appropriate screws.
- Assemble the Side Shelving Unit: Depending on your preferred side (left or right), attach the metal frame for the shelving unit to the main desk frame. Then, insert the two shelf boards into their designated slots and secure them.
- Install the Monitor Stand: Place the elevated monitor stand on the main desktop, aligning it with the pre-drilled holes. Secure it with screws. This creates the two-height desktop design.
