The second one was also with a foot box. I don't know if it will work without a high side.
On my hammock the net circles about 75% of the way around. The question would be, without a high side, if the net is wide enough to wrap over and around you and still pop back up on the net side? That would be the only reason I can think of why it might not, and you could always sew another foot or two of width to your net if it is a problem.
