Bed help

I’ve been with my boyfriend for 4 years and this whole time we’ve had a twin bed, I’m officially over it and ready to buy a new bed MYSELF. My shoulders don’t like being crammed all of the time! With that said, I don’t know which size bed to get I would like a full bc our room is small but maybe that’s too small as well? So maybe a Queen.

.

I’m 130 lbs and he’s around 180 we can both fit on the twin just uncomfortably.

.

Can you tell me what you & your S/O sleep on? Plz and thank you. (Also I live an hour away from the nearest mattress stores so I can’t just go and figure it out on my own just yet)

EDIT: a king would take up our entire room 🤣
