When my friend moved hers the first time, she had her daughter "help" and it did not go well for any of them. She has the Grace frame made up of two 6-foot segments. Some of the rails were slightly twisted and bent before it was discovered that the reason they weren't coming apart is because they were attached...
When we set it up again, we were able to turn around the worst two twists and put them to the outside because the center was otherwise buckled.
We really needed the 3 foot long level we had. It turned out her new house had a slight dip in the floor and despite trying to adjust the feet, eventually we got a piece of cardboard to fill in the low spot. Other than that, as two awkward 60-ish somethings we were able to do the lifting and all that ourselves -- but it definitely was better with two. Don't know how well one could do it.
