I find it weird that low weight is one of the main selling points of this product, but they don't say how much it is.

Yes, weird. I also liked this part:

Embers from a fire won’t burn the surface (If removed quickly).

I think that is true for many surface materials, and that "quickly" is doing a lot of work in that sentence. It also completely fails to communicate whether or not a carbon fiber chair is "safe enough" around an open fire. Annoying.

It's not made out of thermoplastic so probably you don't need to remove them that "quickly". Just not let them sit on there.

After digging around, the FAQ says "approximately 2 lb"

Obviously they don't put the weight on the product main page, that is absolutely heavy.

The Helinox Chair Zero is the standard by which all backpacking chairs are compared https://helinox.com/products/chair-zero - and it is 1 lb 1 oz.

And then some people mod these chairs, like this similar one that was reduced to 13 oz. https://backpackinglight.com/forums/topic/chair-enlightening...

When I heard that a friend had bought one of these for a week long canoe trip we were going on I thought it was absurd. The idea of taking such a home comfort on a camping trip went against everything I felt camping stood for. Then I tried it, then I bought one, now I take it on every camping trip I make.

It's so light it adds basically nothing to your carry weight. It takes seconds to put together. It's insanely comfortable. Kicking back in it after a long day's hike or canoe whilst prodding at the camp fire is such a joy.

I put it alongside my thermarest as a thing I never felt I'd ever buy and now use on every trip.

Definitely worth having something other than the ground to sit on after a long day. I have a couple of light weight 3-legged stools, although they likely wouldn't be considered ultralight, that are light enough for the camping and hiking I do, although you have to sit just right to not crush your balls.
