Yes. You can get full bunk bed frames in a variety of styles. Keep in mind, however, that setting up full bunk beds can be a problem. Full mattresses are a lot wider and heavier than twins. Even twin XL size mattresses can be easier to move than the full.
That means getting a full mattress onto the top bunk may be difficult, especially if it’s a heavier material like latex. Keep this in mind when you’re shopping for and putting together your new bunk beds.
