Pop-up travel cot?

[elk4baby]

Hi,
I'm looking at getting one of the pop-up cots for traveling and visiting friends.
I've looked at the reviews on Mumsnet and it seems there are three options:
LittleLife Arc 2 (this has a foam mattress, unlike the other two)
Nomad Travel Tent (similar to the Arc2, but with an inflatable mattress)
Bushbaby Eggnest (reviews are really mixed on this one )

I like the idea of the Bushbaby Eggnest, especially considering that some reviewers said it's a better one than the LittleLife and the Nomad. HOWEVER, there were a couple of people who mentioned that it can 'zorb' around a room and is not very stable.

I have a very active 9 month old, who's crawling A LOT and actually likes to stand up in his cot (or anywhere, really). So I am concerned about the Eggnest's 'zorbing' problem ...

Could anyone please advise me on which one you think would work best for a very mobile almost-toddler?

(we're not likely to use it outdoors, btw)

Hi I had the samsonite pop up cot. My ds was crawling around at 4mths, and never had a problem with safety in this cot.
Two negatives on it - 1 I never got the hang of the twisting way to get it back in the carrier, dh could do it instantly. 2 the mattress is thin, so I would always put extra bedding underneath.
