Remove the mattress from the bed frame. It's a Sealy Backsaver Plush mattress in this case

The slats are pushed together by tension of these steel rods. Remove the Philips screw holding them to the central beam.

This shows one of the rods removed. These rods look like they don't do much but the prevent the wooden slats from falling off the frame via tension.

This is another rod removed. There are 3 rods in this frame. The 4th one is missing but is unnecessary.

The central beam can just be lifted off from its bracket and removed. See here the beam is on the floor

Use a hex screwdriver to remove 4 long screws that connect each of the four corners.

See here for the screw to remove. Righty tighty lefty loosey

This is the damaged leg but notice there is no issues with removing that screw either. Do this screw removal to the opposite side. There are only 4 long screws to remove.

When screw is removed, simply pull the headboard from the side panel

Pull side panel from footboard also. Notice the wooden pegs that help support the side panel. Don't lose them.

The other side removed.

The completely disassembled bed frame

One last thing. Don't lose this metal screw hole where the long dark screws go into. They may fall out during transport.
