This could be your chair Emmet, it looks pretty good....I'd like to see that test to 750 lbs! The kind you linked to are heavy and I feel not that comfortable, and just a bit too gimmicky.
I'll stick with my Crazy Creek camp chair, with your legs so near the ground it's like a recliner, and being near the ground you don't need a beer can holder on the armrest, you just put the can on the ground. Same deal with cooking, you don't need a table. I've researched this extensively

1.5 lbs ain't bad either.
One disadvantage of the design: if you are at a gathering with everyone else sitting in normal height lawn chairs, you'll feel like a major geek! So, I have backup conventional sitware for times like that, solo I take the Crazy Creek.
