Using your Elio Leather Cushion is a breeze. Just snap it onto the Elio Chair and you're good to go for a comfortable sitting experience. Here are some things to keep in mind. Don't try to stack the cushions as they're not designed for that. When it comes to weight, make sure not to exceed the 350 - lb capacity. For maintenance, clean it regularly with warm water and mild soap using a soft towel. This will help keep the leather looking great and extend the life of your cushion.
