The thing about the lounger is that it is more narrow, which means it takes up less space. It is also 7.5 ft long, which is plenty of space for two 6' people. I'm 5'8" and my husband is 5'10", and he and I have more than enough room to lie side by side and still have plenty of room above our heads and below our feet.
Honestly, none of these are completely easy to move; you're talking about almost a 100lbs of foam in a big sack! But they are extremely comfortable and totally worth it. We have the lounger, and we find it easy to move because you can just roll it over. However, the Cocoon is very cool because it is multiple seats in one. It's really your preference.
