When determining the right size for your camel back couch, the size of your living room (or other room it will go in) is going to be the indicator. The first thing you have to ensure is that it won't overpower the room or prevent the flow of traffic from occurring. Before shopping, take measurements of the entire room including the wall its going against. Make sure you measure the areas the couch will pass-through, as well, to ensure it will fit through those spaces.
