We have a sleeping loft with a low ceiling.  This has been perfect.    If you fold the larger end under the larger middle and then fold the smaller so the top is against the wall you end up with a longer sitting area.   (Some reviewers folded the 2 smaller pieces back on top of the middle and ended up complaining about not enough room to sit on).   Just fold it correctly and you have plenty of sitting room.    I had no outgassing/smell issues and slept on it in the evening after opening it up in the afternoon.    Just perfect for our needs...comfortable sleep.  

Pros: Folds in a nice seat.   Comfortable sleeping
