We recently purchased this and put it together (two of us) and it was pretty easy to do overall. A few times it took some effort to get pieces into an opening but with patience and a rubber mallet to help we did it. I think it would be much more stressful if only one person tried to do it. The only reason I didn’t give 5 stars is because there is only ground stakes/mounts but we put it on our deck and there are no secures/brackets included for this. I looked online and it’s an extra $100 for four post holders that can be screwed into wood, etc. Yikes...we went and bought our own brackets to use from hardware store for under $10. We also added privacy lattice to it. So it looks real nice.  Overall we love this arbour and highly recommend.
