I give it a 5 because I like it - it's as sturdy as a metal bench can be expected to be, it's beautiful. Assembly was easy, maybe 20 minutes, a second person holding it would be helpful but not necessary.

Two issues though. One of the nuts was missing, they sent me a replacement so I'm good. Be careful when unpacking, sometimes they are rolling around the box.
Second issue: the measurements Watfair provides are not right. Here are the approximate correct ones in inches: seat height 17", highest point 38" from ground, front feet 30" apart, middle feet 47" apart, back feet 2" apart. Front feet line is 15" from middle, middle line 8" from back. Widest wing to wing is 60".
