I want to buy a three-level bunk bed for my children. Can anyone recommend a good place to purchase this item?

You can purchase the long black screw assembly from the manufacturer of the Fashion Bed Group Bunk Bed. You can contact them directly to inquire about purchasing the part.

Question edited for clarity, albeit a year late.

Alan. There are instructions for converting from a bunk bed into twins, but nothing in reverse. It looks like the parts came with it as bunk beds and you removed them for twins.

This would be an easy job for a carpenter to make the conversion

He could also make a ladder or you can buy one for $79.
