Child pacifying elastic chair in accordance with embodiments of the invention are disclosed. In one embodiment, an elastic chair for supporting a user while soothing a child, the elastic chair comprising: a ball body having a spherical configuration, wherein the ball body allows the user to bounce vertically; a back rest connected to the ball body, wherein the back rest provides the user a support structure to lean against; at least one arm rest connected to the ball body, wherein the at least one arm rest provides the user a place to rest at one of user's arms; and a plurality of feet connected to the ball body, wherein the plurality of feet provide stabilization for the ball body such that horizontal motion of the ball body is restricted while the user bounces vertically atop the first surface.

An adjustable chair frame with a back and seating surfaces that flex to conform to the shape, weight and movement of an occupant is disclosed. The chair form and proportions provide for a recumbent position that disperses the weight of the occupant more evenly, thereby reducing external and internal physiological point loading. The form also provides ergonomic articulation to minimize internal physiological stresses such as neck/back vertebral compression. Eccentric connections driven by a motor assembly allow positioning adjustment of the components of the chair. Additionally, an air pump assembly may be included to automatically adjust one or more air bladders provided on the interior of the chair frame.

A pneumatic lounging system includes an inflatable support unit and an inflatable unit. The inflatable support unit includes an inward layer, an outward layer, and a support air nozzle. The inward layer and the outward layer define an air cavity, and the outward layer is attached to the inward layer. The support air nozzle is attached and adapted to provide direct fluid communication of air with the air cavity. The inflatable unit includes an inward wall, an outward wall, and an air nozzle. The inward wall and the outward wall define at least one air chamber, and the inward wall is attached to the outward layer. The air nozzle is adapted to provide direct fluid communication of air with one of the at least one air chamber. There is no fluid communication between the inflatable support unit and the first inflatable unit.

Light weight, easily stowed in small spaces inflatable chairs, pads, and flotation devices all from a relatively simple combination of at least two inflatable drop stitch panels which can be held in position relative to each other by use of straps, or in other embodiments, by additional inflatable side panels which provide arms and support to hold the chair upright on the ground. Simple hinges can be used to connect the panels together in desired configurations, either as fixed deployments or as adjustable and convertible deployments, where in one deployment, the panels for a chair, and in another, a flat pad, which can be used as a float or as a ground pad for camping.

A pneumatic device for varying a contour of a seat bearing surface includes a carrier foil TF composed of a first and a second foil ply which are arranged adjacent to one another. The pneumatic device has a first bladder for varying the contour of the seat bearing surface, including a bladder chamber which can be filled with pressure medium (DM). The pneumatic device furthermore has a first pressure medium line connected to the first bladder and which is formed by connection of the first and second foil plies along a line-side connection seam to create a pressure medium connection to the bladder chamber of the first bladder. One foil ply has, in the region of the first bladder, an opening in order to form a pressure medium channel to a further bladder, which can be filled with pressure medium and is connected to one of the foil plies.

One aspect of the invention provides a structure including one or more strut tubes adapted and configured to receive and hold a granular material. The one or more strut tubes further include compression means for applying at least compression to the granular material after loading. Another aspect of the invention provides a method of erecting a structure. The method includes: inflating one or more strut tubes with a fluid; displacing the fluid with granular material; and compressing the granular material.

Products and methods are provided for inflatable structures. In various exemplary embodiments, an inflatable structure is provided with multiple variable chambers including a first variable chamber and a second variable chamber. A first boundary envelope defines the first variable chamber and a second boundary envelope defines the second variable chamber. The first and second boundary envelopes separate the first chamber from the second chamber. The first and second variable chambers are defined by an operative scale that may differ by an order of magnitude between the first and second variable chambers.
