Assembling your Helinox chair is quick and easy. The shock-corded frame will virtually self-assemble – just be sure all the poles are fully inserted into the hubs. Always fit the seat to the upper rear poles first. Then, lay the chair on its back and use your body weight to flex the lower seat poles into the last two pockets. Brand new seats can be a little tight and the durable fabric helps prevent the seat from sagging over time. But don't worry, the more you use your chairs, the easier they'll be to assemble.
