Just after some feedback on mats or air beds for camping purposes. I have a Oztent RV4, so have 2.4mx2.4m of ground/floor space. Was thinking a queen size mat of some sort... Looked at a few options below. My 4 year old will be starting to go away with me so instead of getting him his own swag, for now figured id just use the OZtent since we got it. Thus far ive been sleeping on the stretcher in the OZtent. But instead of getting another stretcher for him(more things to carry), I figured just a ground mat might suffice.... As well as comfort, Im guessing a lot of these would be very cumbersome to roll up / pack up.

Any thoughts or recommendations most welcome!
A lot of choice out there...

Some examples...
Simple foam camping matress from Clarke Rubber. 100-150mm.

Another example is self inflating Oztrail mat...
