Well, I have exactly that green one pictured in your post. I've had it for about 1.5 years, and have used it on a handful of camping trips. OK, I like the comfort, the pillow, the backpack-ness, and it has a couple-few recline positions, which is nice. I also like the wood arm rests...I carve names of places I visit into them when sitting by campfire.
Now, it does not actually appear/feel all that sturdy, and there are some rather thin, weak-looking aluminum plate components here & there built into the reclining mechanism...but I haven't collapsed it yet. I'm 6'2", 190, and have tried plopping hard into the chair many times, and it is still working fine. Perhaps if you hit it at the wrong angle, it might break...I dunno.
FYI, I have seen a similar chair at REI which, IMO, is MUCH sturdier than the one I have...however it was quite a bit higher-priced than mine (I believe I paid around $30).
Anyways, hope this helps.
