I was a little concerned that the assembly would be too difficult.  But while it was time consuming, it was doable.  The other reviews which stated that the holes didn't properly align was not true in our case.  My husband did realize after tightening some of the bolts that some were longer than others, which it did not indicate in the directions.  This would have been nice to know at the beginning bc the longer bolts should be used for the two cross bars.  However, everything else about the assembly was straightforward.  And the kids (newly 8 and 5/almost 6) LOVE the new hammock as it's fun for both of them together in there as well as individually.  Once assembled it's very safe and secure.
