  • Patent number: 11707134
    Abstract: A packable chair is provided that is transformable between multiple configurations, including a storage configuration and a chair configuration. In the storage configuration, the portions of the packable chair are arranged and fastened to define an enclosed volume in which containers and other items can be stored. A user can wear the packable chair like a backpack in this storage configuration to transport the contents from, for example, a car to a location on a beach. Then, the contents can be removed from the enclosed volume, and the portions can be rearranged to form the chair configuration where a user can lounge and access the contents of the containers. The chair is also capable of achieving a travel configuration in which the chair can be worn as a backpack for convenient transportation without stowing a user's items.
