They are beautiful and solid.  Love the red for that pop of colour.  Easy assembly, done in less that 15 minutes.  The bolts are heavy duty steel.  I just took some flat black metal paint and touched them with a brush, now they blend in with the stool and the distressed look.  One stool have a little imperfection in the paint but I only need three so that one is a spare.  Love them and would recommend them.
