I don't have a lot new to add to this thread, I mostly want to reiterate the advice already given... I haven't used a chair a kit since the Helinox came out. The Helinox actually weighs less than the 25" Thermarest chair kit I had I imagine folding the pads does cause wear and tear, though I've never experienced obvious failure related to the chair kit. I have had a total of 4 pads replaced due to failure at the seam. Two from REI and two from Big Agnes. They readily accepted that seam failure is not user error (like a puncture would be). All four pads were several years old when replaced.
