This chai is exactly what I needed for lounging on during the day and then sleeping at night. It is firm foam, which I like for sleeping on. The leather is fake, but supposedly if I treat it like leather with conditioners, it will  last pretty long. It is soft and supple and i like the feel of it even though it is artificial. The mechanism for folding out seems simple and hopefully will last a long time because of this. You just pull forward on the back till you hear a click to release and then if folds flat. I do have it up against a wall, so that might help support the mechanism. I can not see it inside the construction. All stitching seems done well and there are no bars that you feel on your body when sleeping. I am sleeping comfortable on it every night so far!
