This Comfy Sack is fantastic. It's very big, big enough for two adults to lounge or several kids. It's become my daughter's go-to spot for doing her homework in her room. It's very big and very heavy, so it's not something you'll want to move around from room to room as an ad hoc lounging station. Think of it as a piece of furniture that has to more or less stay put.The Comfy Sack comes in a big, heavy box that would be hard for one person to lift. I didn't lift it. I rolled it inside and rolled it up the stairway myself. When you open the box, you see the heavy, zippered bag that the Comfy Sack comes in. Open that up (you can throw it out, as you won't need it again) and you see what looks like plastic-wrapped, dehydrated vomit. You're to remove the plastic wrap and start breaking the vomit up into smaller chunks to aid in the Comfy Sack's expansion. My daughter and I set the Comfy Sack up together, and it took us about 45 minutes, with breaks--because breaking up the chunks was surprisingly tiring. (It's possible, though, that we broke it up more than we had to.) Once you've broken it up, you slip it into its heavy, zippered casing, and you're good to go, though the bag will continue to expand for a while.The Comfy Sack is very comfortable. (I actually fell asleep on it the other day.) The zippered case you slip it into is soft and seems very sturdy. I imagine you could take it off and wash it when necessary. This bag is great for a kid's room or play room. Just make sure you have enough room for it, as it's quite large.
