Abstract
A collapsible flotation device is provided that uses a coilable spring coupled to a panel to collapse the device when the spring is coiled, and to expand the device when the spring is uncoiled configuration. The spring can be contained within a sleeve along the outer portion of the panel. A support member that traverses the panel is provided. An inflatable bladder disposed about a part of the outer portion of the panel and coupled to the support member buoyantly supports a body weight of a user. The combination of the inflatable bladder and the support member provide support for a user in a seated position on the panel. Many configurations are disclosed, including a multi-user collapsible flotation device, multiple connected single-user flotation devices, and so forth. A back support member and a headrest, both of which can be inflatable, provide additional support for a user to maintain a seated position on the panel. A foot support member is provided for the comfort of the user.
