Great mattress and super comfortable, but definitely not compact. We got the full size to use for camping. It's huge! 

It comes in a small box and nice duffel bag, but good luck in trying to get it back into that bag! We used 3 ratchet straps to get it back down to a size small enough to take on our trip. Still didn't fit in the bag but that's OK. Looking forward to a good nights sleep on it while camping, but not looking forward to having to ratchet it back down to size to transport home.
