A while back someone at a picnic I went to had a Helinox chair, which I found quite interesting. I don't recall if they had the Zero or the One, though now that I look at the pictures again, I think they had the Zero.
I looked about for cheaper alternatives, and discovered the Zephyr Chair which deadset looks almost identical (other than the back is solid material and not mesh).
It is about 400g heavier packed, only has a load capacity of 110kg vs 145kg, and probably only enjoys 1 year warranty instead of 5.
The Helinox also has a bajillion accessories, which I do not know if they might be compatible with this knockoff - given the dimensions are a bit off, I suspect they are not.
Either way, this was only $49.99 vs $149, and given I didn't need a camping chair that often, I doubt I'll miss not having those accessories.
I bought it about a week ago, and have been breaking it in and it's been quite good. You will find it very difficult to put together the first few goes as the material needs to stretch a little first, but it gets easier. My tip is to do two opposite corners first, then the remaining short section, then finally the last long section as the long sections have a pouch like area to pull on, allowing you to exert the necessary force.
Can't beat the $5 camping chair from kmart. They last forever too. https://www.kmart.com.au/product/basic-camp-chair/2127463
