I was replacing a fake leather convertible futon that everyone refused to sleep on because it was just too hard.  So this sofa really did the trick.  The felt/suede feel is nice and it's much more comfortable than fake leather.  It seems built well, and wasn't too difficult to put together.   Immediately after assembly some of the cushions look a little frumpy because they came in compressed air packages.  I am hoping they expand a little over time.  The backrest is adjustable on each side, but unfortunately you have to place it all the way down first to be able to adjust, so if your sofa is against a wall you'll have to move it out first.
