the Helinox ground chair isn't bad but their other ones remind me of the folding toilet seat that I always take on llama pack trips. Those little legs sink into the ground and roll you over backwards if you're not careful.
It's too bad that these are so blasted heavy. You wouldn't want to backpack one. I have 2 that I use on llama trips and they're very comfortable, not to mention being 1/3 the price of the ultalight chairs.

But at $110.00 That will require some real need.
I do like it though.
