Can teens sit on single beds/bunk beds?

They can sit and do their homework on single beds, don't know about laptops. I saw James Turner's sim sit on a single bed and do his homework in his video.

Maybe it is just the top bunk bed it doesn’t work on then. I am assuming you click the bed and it says sit….

Clicking the bed, they just sit on it. The JT video there was no table to do homework on. He clicked on the book in sim's inventory and the sim sat on the bed to do his homework. So if there's no table or desk on the lot, click on the laptop. Hopefully the sim will sit on the bed with the laptop.

Two of them can sit on a single bed for a pillow fight. Yeah, that's my Global Superstar, screen right, in the sweater and cap. The one cowering is his next younger brother. LOL Erik taught him a lesson.
