i came across these while looking for some portable options last week! we're relocating to washington state with a short trip to rhode island and need something for two small kiddos who currently sleep in cribs.
but i don't think this will work for our 2 yr old... might be too small. may have to work out some sort of rail system on a 'big girl bed' or something.
i've read a few online posts about this and most people use lots of pillows around the perimeter of a sofa bed or whatever... but i think that's a little overboard. i've also seen toddler sized air mattresses - but i have a curious adventurer that won't stay put!
