My Helinox chair came today. I'm 6',195 lbs. and it fits fine. Quality of construction and materials seem to be excellent. It sways some but it's a 2 lb. chair,I don't expect rock solid. I tried leaning on the back legs, then front legs, then side legs to see if anything would give way but all held up. I put my 40 lb. dog in my lap and did the same,all went well. As for the plastic joints,they seem to be well designed and well built. The $15 discount store chair I've used for 12 plus years has smaller plastic joints and has held up fine(but it's huge and weighs about 8 lbs.). I got the Helinox for the taller height and the price wasn't bad. I thought I would see how it looked and sat and ship it back if I didn't like it. For $72, I'm happy and plan to keep it.
