Better to be two to build it ... it's more fun! But alone it is possible. Once the swing is complete and installed, one sits or lies down there ... in his garden in the shade. The star is less for scooping the "roof" on rainy days; think to remove the mattress. It lacks a little wax to protect the top, and if I really wanted to quibble, a thicker mattress, especially when two sets. FYI, we began to 4 above (two adults and two teenagers) without disaster; I feel solid. As my wife would say, it was a good idea.
