The mattresses look to be 140cm so I don't fancy your chances.
What are you going to do when they need a single bed?

That's what I fear Paisley. As for the single bed it's a case of cross that bridge when we get to it. Hopefully might be in a position to move by then?

Just go for a normal cot.
It gives you a couple of years to think about it.

If it's any use, the Ikea cots are sort of cotbed like in that they're cot sized, but a side comes off and they do some bedding for them so that you can use as a bed.

We're planning on doing this as DS1 will start off in a tiny bedroom, and we don't know if we're going to have DC2. If we do we'll have to cross that bridge as you say, but a second DC could use the cot and we'll need to buy a bed for DS1, so there's no loss!
