This was purchased as a gift in March 2021. Thought the assembly would take an army to put together. It didn’t. It took one full time adult, one part time adult, a part time 10 yr old granddaughter.  But then it took four strong adults to lift it in place. Many thanks to strong younger men. Can’t say how many hours it took over the course of a week as this was done when time permitted. It was stunning when it was finished.  Very popular as the 12x14 size sells fast. The arch design has changed since last year. Could make it easier to assemble. Definitely recommend.
