Abstract
A device comprises a spring and a sleeve. The spring is configured to form a closed loop. The spring is moveable between a coiled configuration when the spring is collapsed and an uncoiled configuration when the spring is expanded. The spring defines a circumference while in the uncoiled configuration. The spring is disposed within the sleeve.

A flotation apparatus, comprising:
- a panel having a first end portion and a second end portion opposite the first end portion, the panel having an interior region and an outer region disposed about the interior region, the panel having a maximum length greater than a maximum width of the panel,
- the outer region having an inner perimeter portion, the outer region including a first inflatable chamber, the first inflatable chamber, when inflated, having a centerline that is curved;
- the interior region including a liquid permeable material having an outer perimeter portion fixedly coupled to the inner perimeter portion of the outer region, the interior region including a second inflatable chamber having an end portion coupled to the outer region of the panel such that the second inflatable chamber is disposed between the first end portion of the panel and the second end portion of the panel, the second inflatable chamber, when inflated, having a centerline that is linear.
A flotation apparatus, comprising:
- a panel having an interior region and an outer region disposed about the interior region,
- the interior region including a mesh material having an outer perimeter portion, the interior region having a maximum length greater than a maximum width of the interior region,
- the outer region including a first layer of material and a second layer of material and defining a pocket between the first layer of material and the second layer of material, an inner perimeter portion of each of the first layer of material and the second layer of material being fixedly coupled to the outer perimeter portion of the mesh material of the interior region;
- a first inflatable bladder disposed within the pocket between the first layer of material and the second layer of material of the outer region of the panel;
- a second inflatable bladder disposed in the interior region such that a centerline of the second inflatable bladder is disposed parallel to the maximum width of the apparatus, the mesh material of the interior region being coupled to the second inflatable bladder;
- and
- a third inflatable bladder having an end portion coupled to the outer region of the panel between a first end portion of the panel and a second end portion of the panel such that the mesh material is disposed (1) between the second inflatable bladder and the first end portion of the panel, (2) between the second inflatable bladder and the third inflatable bladder, and (3) between the third inflatable bladder and the second end portion of the panel opposite the first end portion of the panel,
- the flotation apparatus sized and shaped to support a weight of a user of the flotation apparatus when the flotation apparatus is disposed on water, at least one of the first inflatable bladder and the second inflatable bladder is inflated, and the user is disposed on the flotation apparatus.
