Do you mean 2 per join or 2 per piece (one at each end)?

2 per piece is too brave for me, 2 per join I'd say probably fine, but if you can fit 3 per join I think you should just to be safe

Ideally, you'd be doing a bridle joint or even just a half-lap so you've got face grain to glue to

no sorry 2 per join sorry for not being clear.

If you're happy to laminate around a jig, that will be the strongest way by far. Joins are a potential failure point and the laminated construction will be more springy

I was trying to avoid that as I have never done anything that large in laminations but looks like I may be forced to.

I would be going with laminations also due to the risk of injury if the jointed frame failed. Laminated structures are very strong. The thinner your lams are the easier it is to bend into shape and the tighter bends can be made. I would aim for about 3mm or less lams or as low as your thicknesser will go. Use a good epoxy like techniglue. It works well for archery bows so should be fine for this. As to overall cross section size of the bendy frame you should take a look at one of those ikea chairs with the laminated frame. Thats holding the same weight.

I would also suggest a laminated approach for the diagram that you had put up.

I might offer a suggestion that the curve drawn might not be needed to be that big a sweep. You are connecting at one point so you only need to ensure that when fully loaded the hammock does not contact the frame.

I built a rocking chair with a similar joint. Rocker WIP It was solid Jarrah sections about 40mm by up to 80mm on the biggest joints. I used one large floating tenon about 10mm thick and as large as possible. Each side of the rocker, with no other support (before final assembly), could very easily support my weight with no movement whatsoever.
I'd say just go for it.
