Using this chair is super easy. Just take it out of the carrying sack and let the internal bungee cord do its job to self - assemble the poles. Then, simply unfold it and you're ready to sit. When it comes to weight, it can handle up to 145 kg, so most people can use it comfortably. For transport, it packs down small and light, making it a great addition to your backpack or bag. As for maintenance, since the seat and sack are made of ripstop nylon, you can hand - wash them when they get dirty. Just use mild soap and water, then let them line - dry. Avoid using harsh chemicals or machine - washing as this might damage the material. Also, try to keep it away from sharp objects to prevent rips.
