The uprights hinge back to being the size of 2 stacked 2x3s so I can store them in the shed for the winter, and overall it feels pretty solid. I might work on a variation to hang both kid hammocks side by side using 2 lines on each end instead of one; they don't weigh combined as much as 1 adult, so I should be able to knock the expense down a bit.

It is amusing how much hardware you find in the stores that say "not for use with athletic equipment or for supporting human weight"

If I fall the 2ft or so to the ground, its my own fault for not overbuilding it to begin with!
