The assembly was very easy & didn’t require any tools.  The “sturdiness” of the materials used in mfg seem reasonably solid.

There is one measurement that we strongly recommend you consider before purchasing…. Check your measurements from seat to top of chair’s back before you buy this one!  If your torso is equivalent to the average 4 to 5 foot tall person, you are probably fine.  If you are any taller than 5 feet tall, you are NOT likely to be able to rest your head against the chair’s back.  You will more likely end up looking straight up at your ceiling whenever you allow your head to lean into the back of the chair!  This chair is essentially made for people far shorter than the average American adult.  If you are unusually short or you are purchasing for a non-adult, this may be a great choice for you.
