Knowing that I am somewhat incapable of travelling light, I didn't want a cot that added another 7kg or so to my luggage. This cot is a pop-up cot (you just need to push 4 rods into the seams, very easily) and the entire thing, in it's bag, weighs just 2.17kg.
It's a nifty little thing, and takes up far less space than the traditional travel cot. Insect nets are in-built and the cot is basically a little insect-proof bubble, thanks to the zipped "door" on the front. However it is at ground level, so you may want to keep that in mind if you have back problems.
The mattress is included but is in my opinion too thin. There is an inflatable mattress you can buy separately but it is expensive and adds weight and I have not read a single good review, so I opted out. What we did was fold a blanket underneath the mattress for extra padding and my daughter happily slept in it for over a week when we were away.
