It's a really nice couch...practical and comfortable at the same time.  The sides attach and detach very easily.  The bed portion of it folds out easily and has a very smooth feel to it when extending it out.  Once the bed is extended all the way out and the back is reclined all the way down, the bed is large enough for to lay down and not be hanging off.  The back can also be set at different angles so it can be reclined as little or as much as you want.  Overall, great quality and great buy.  Would recommend!
