Helinox chair owners, these stabilizing feet are an absolute game-changer if you've ever struggled with your camping chair sinking into soft ground! This set of four Vibram rubber ball feet slides right onto your Helinox chair legs (they're compatible with Chair One, Chair Two, Chair Zero, and most other Helinox models). The 45mm diameter gives you way more surface area than the standard tiny chair feet, which means no more sinking into sand, mud, grass, or gravel. Made from durable Vibram rubber (the same company that makes premium hiking boot soles), these things are tough enough to handle rocks, rough terrain, and years of use. Installation is stupidly easy - just push them onto your existing chair legs, no tools required. They provide much better stability on uneven ground, so you're not constantly adjusting or worrying about tipping over. When you're done, they pull off easily and store in the included mesh bag, adding almost no weight or bulk to your pack. At just 9 ounces for the set, you'll barely notice them in your gear. If you love your Helinox chair but hate how it performs on soft surfaces, these rubber feet are worth every penny for the improved stability and peace of mind they provide. Seriously, once you try them, you'll never want to camp without them again!
