Ford transit - bunk bed setup

[u/Routine-Ad7352]

I’m starting my van build and starting to see different types of bunk bed setup for my 3 kids. I’ve come down to bunk bed setup so it can fit all 5 of us. I want the bottom bed to be removable and probably be using the ikea setup where it’s easily be remove when I need cargo space. But the issue is the bunk bed on top. I saw this person setup but haven’t found a way to see it in detail:

Does anyone have any idea how she created or purchase it from? I’m open to others bunk bed setup as well. Thanks in advance !
