I agree with the others that for a 2 yo, you can easily improvise a bed, but I do want to say that we had the second bed that you originally linked to (the blue inflatable one), and I actually really liked it. We almost never took the pump with us - it's just extra space and weight, and an adult can easily blow up the bed in < 10 minutes (although I was always a little winded at the end!). Rolled tightly, the uninflated bed takes up about 40% of a rollaboard.
We hauled that bed around three continents with us, and it finally sprung a leak after about a year of decently heavy use. It is a comfortable bed, and my 2 yo daughter did really well in it. A heavy tosser-and-turner could roll out, but the sides are high enough to contain most sleepers.
