Have you seen this? It is called the Lamzac Hangout and it is a small, envelope-sized pouch that converts to a lounge with “a single flick of the wrist.” This would be a lot lighter and more comfortable than a lounge chair and would solve that camping problem of never having a comfortable seat for serious reading.

Just swing the lightweight bag through the air to create a full size lounge chair. When you’re done lounging easily deflate the bag and roll it up to fit the small carrying bag.

It makes a lounge for one or sofa for two.
