I definitely like the quick assembly. Where I think it needs to improve is the weight (~2 lbs). You’re paying big bucks for carbon, but then it’s about twice the weight of the lightest chairs on the market, so it’s a bit hard to justify paying 2x for something that also weighs 2x.
Pack frames on ultralight packs are usually in the range of about 100g / 3 oz, so the current chair would be massively stronger than you need for an ultralight pack frame. The potential ‘win’ here eliminating a 3oz frame, but if you add 1 lbs in chair weight to do that, you’re not ahead. It’s quite overkill as a frame, so it would be a better fit in load hauling/hunting pack where you do actually need a heavy frame. However, using the chair as a frame is hard to do because it would only work for a specific pack(s). So you’d have to like the chair and like the pack. I don’t think that’s viable commercially because it is a very small group of people that would simultaneously want this chair and want exactly the 1 or 2 models of pack designed to work with it. Most people will have another pack they prefer for various reason.
Overall, I don’t think the frame application is going to work out that well. Just too many challenges of making it work well while being rapid removable, and tiny niche people that want exactly that pack, and it’s way overkill as a UL frame. I think the best path forward is to redesign a lighter version that reduces the max weight from 400 lbs to 250 lbs but hopefully gets it closer to 1 lbs and addresses the awkward packed shape in another way (e.g. make it fold?). If it was 1 lbs and folding that starts to look pretty good.
