We have a air mattress sofa in our 09 30sk. Yes it is more comfortable than a regular sofa bed. It comes with it's own pump (12v I think). It is however a pain to set up & take down & I can't help but wonder about it's durability! It is the only option to the standard J sofa offered by Crossroads ,I thinks it was about $500.
