Joists loft bed

If you have a flat unventilated board and place the mattress on top, you will get mold.

You mean like the one I attached in my first post but more detailed?

Yes. Where were you planning to have the studs, etc.

I came across this older discussion and wanted to add that I’ve had good results using simple ventilation wedges or thin slats under the mattress. They’re cheap and keep the air moving without raising the mattress too much. Has anyone here tried drilling a few holes in the board itself to boost airflow?

Me. When I was a student me and my buddies built several loft beds, also with perforated boards. I think your idea is as good, as long it does not create waviness in the mattress.
My best loft bed was hinged and could be upfolded when more space under was needed.

I had the same struggle picking something sturdy that wouldn’t eat up the whole room, and a kids bunk bed https://www.coolkidsbed.com/product-category/bunk-bed ended up being the easiest way to free up floor space. I liked that some options had built-in desks and storage, so I didn’t need extra furniture. The price range was manageable too, so I could focus more on features than stretching my budget.
