OMG i went to KMart and got a mattress that has a built in POWER pump. it's by swiss gear. the batteries have a compartment INSIDE the mattress and you attach the pump to the space next to it and go to town. it does the work in 1/16th the time of a foot pump AND...if it's not full enough you can then do the hand pump bit on the mattress. and it only cost me $25 for a full!
