I was given this second-hand cot bed but didn't actually use it as I was gifted a new one in the end.
It's free to a good home. Comes with a 70 by 140cm mattress.
I don't have the exact model name but it looks like the one in the picture below, except of course it is not in new condition since it was given to me second-hand. Still, it is sturdy and will definitely be useful for a few more years.
