Nice little chair. Had problems assembling it as it seems to take 2 people, but I had no help. I had to ignore the instructions on assembling the backrest first as I just could not assemble the bottom after that. Had to do the bottom first then it was Wrestle-Mania trying to get that backrest installed but I finally go the 3 count, got the chair to tap out :-). The chair rocks back and fourth and the tension is adjustable on that, though it wont lock in a reclined position it only locks to keep it from rocking back, it adjust up and down. What I don`t like is I can`t fall asleep on it like the chair it replaced, which is worn out backs just too short for that nothing to rest my head on. Cushion seems o k.  Who knows how long it will last? And almost forgot? had trouble fitting the wheels on had to use a little axle grease.
