Im pretty sure they are all the same set up as well. I too have the Bruin one and it has been fantastic, so fantastic in fact that DS won't sleep in his brand new $200 cot only his $75 portacot! They don't have a matress as such just a padded bottom, DS was fine sleeping on the padded bottom with his sheepskin on top til he was about 9 months then i just cut up his cot foam matress (as he wasn't interested in sleeping in his cot) and now his portacot is his full-time bed.

Our portacot was REALLY difficult and incredibly frustrating to try and put up and take down for the first 8 or so times that we used it, now that we have been using it for so long it is extremely simple to do as the joints aren't so stiff.
