I was initially impressed by these chairs when I pulled them out of the box - the plastic material appeared sturdy and color (red) very attractive.  Assembly was pretty simple (provided you have a cordless screwdriver).  However...on two of my chairs, from the get-go, the arm-rests seemed very flexible and not attached to the frames well.  Then, when folding the chairs for the FIRST TIME, two of the arm-rests tore straight off.  Seems reasonable that you could pick up a chair by the arm rests..right?  They are held to the frames very weakly by four self tapping screws.  Not impressed by this aspect of the construction at all, and makes me worry about how long they will last.  Shame, as overall the design is great, they are very attractive, and are comfortable to sit in.   I'll keep these, and likely add additional more substantial fasteners all around, but I probably would not purchase these again due to the construction
