"What Our Gearhead® Experts Are Saying:""I use the Ground Sheet for Chair One anytime I’m camping on soft ground or uneven terrain. It keeps my chair from sinking, shifting, or wobbling, especially on sand or loose dirt. It’s super light, packs down small, and attaches securely so I don’t have to think about it once it’s on.""We count on the Ground Sheet for Chair One when we want a reliably stable seat no matter where we set up camp—riverbanks, forest duff, desert sand, or anywhere in between. Designed to work seamlessly with Helinox’s iconic portable chairs, this ground sheet spreads out the load to keep the legs from sinking, shifting, or rocking on softer terrain. Durable, all-weather monofilament mesh keeps weight low without sacrificing strength, and the reinforced attachment loops make securing the chair simple and dependable. When the wind kicks up, the sheet even helps anchor the setup by providing a broader base. And when it’s time to pack out, the whole system folds down flat and disappears into our gear kit until the next campsite calls."
