SO HARD TO ASSEMBLE!! Honestly All you have to do is put the back on the chair but the holes do not line up and it requires more than one person to assemble these chairs. You really have to muscle the back of the chair to get the holes to line up. We ordered four chairs and they were all the same hard to assemble.Once put together these chairs are comfortable sturdy and of excellent quality. We love them for outdoor patio.  Highly recommend.
