At no time will the 2 beds be attached to one another. You are going to construct the bed in two parts and they’re likely to slide into each other. If you’re able to weld then great, you’ll be able to make the specific bed for your conversion.
Basically, you’re likely to build two beds, but one portion of the bed will have 6 legs and it won’t move and the other part will just have three legs and it’ll move. You might have to design and construct your own, but I think that it’ll be well worth it if it means fitting in an additional bed or two! Platform beds are an easy solution.
If you own a bunk bed but don’t utilize it, you probably feel the exact same way. These things seldom make either excellent beds or superior sofas. I would ensure you can try out any type of folding bed before buying it.
