Question: The seat looks like it may sag. Does it after time?
Document: We needed a heavy-duty folding chair for a variety of purposes. We carry these to lacrosse games and hope to use these for camping and fishing in the not-too-distant future. I like the cup and pouches on either side. The poles are sturdy and the carrying bag is well-made as well. Very pleased.
this chair is amazing. comfortable durable easy to setup. Very good product worth the price! And the cup holders are a plus for sure!
great chair, well designed and comfortable. Clearly designed for the heftier among us. Only issue is you are short the chair height at the front is high enough that your feet will not touch the ground (say &#60;5'2' ish). I'm 6'2&#34; so have no issues.
What else can I say? It's well built and comphy. Worth every dime spent on it. Shipping was a little slow, but I got it so no big deal.
Well, yes, you do! For a couple of fairly hefty folks, this chair didn't stick to our butts when we stand up. I carried a cheaper model half way around a campsite stuck to my backside before I could pry it off. Extremely comfortable. Extremely well built! Setup is good and stiff as one would expect in a new chair. This chair is very well padded and just dang dang well built. I would say I would buy another one but I won't have to.
It is nice but it takes a lot of effort to close it. It is bulky but if you can carry it around in a cart, and a lot of cargo space in your vehicle then it is a good chair to use.
Chair is comfortable and heavy duty. This has cup holders on both sides of the chair..holding one on each side. The back top side of the chair is very comfy for you head, works as a pillow. Nice touch&#8230;  Great chair to camp with and especially fish with !! Get it !! It works !! !
