Too soon to say how well this piece will hold up, but I wanted to affirm the previous reviews that say the instructions are absolutely useless when it comes to putting the arms on. A million thanks to the reviewer who mentioned that you have to slide the arms *up* from the bottom of the tracks instead of down from the top. Would never have figured that out from the instructions, which are maddeningly vague on the subject. I do really like the different configuration options for lounging, especially the ability to pull the bottom third out for a footrest while keeping the back upright. Haven't had anyone sleep on it yet, but as a couch, it is definitely extremely firm. I'm coping by adding throw pillows and crossing my fingers it relaxes a little over time.
