One of my family members has one. It is long and so is the storage bag, something to consider on how much room you have to pack it. The canvas is thick and inside is nice and dark so it is easy to sleep past sunrise. They are fairly spacious for 2 to sleep in. The newer ones come with a thicker mattress/bedding to sleep on, but they haven't complained about theirs. It just depends on how soft you like your bed. Very quick to setup. The delivery time was quick.
I got one of these before they started putting the Kings name on. Mine has Roo's Systems on it. Same swag. Its big its good. We put a self inflatable matress under to add to comfort. Mainly cause my back is RS. They do smaller than the double size in the Kings Swags now. Couple of different styles as well. I think they are good value. I also have a couple of Swags from WA which are more basic but more expensive and higher quality canvas but no screen areas. They're all good. I think the Kings Swags will suits a lot of campers. I have seen a lot of them in the back of utes in NSW and QLD.
