Would be 0 for actual use! Just bought 6 and first one out of box would not fit together in step 1 of assembly! Very disappointed.  The pieces look good and seem solid but when the first one of six doesn't go together as it should,  not worth it.  Yes, I followed instructions... not to tighten before all pieces were together.  STILL couldn't get the seat attached to back in STEP ONE of assembly.  The holes do not line up correctly.  They are ALL going back. Not going to unbox anymore and risk hassle of having to pack back up to send back.  So infuriating!
