Abstract
A futon has flexible, foldable, separately tufted covering layers zippered to enclose a pair of pneumatic layers. The pneumatic layers are separately inflatable, co-planar, and foldable along one set of parallel axes, and also foldable at a perpendicular axis along the line between the pneumatic layers.
Claims5
A flexible, foldable futon comprising opposing flexible, foldable, covering layers,
- at least one of said covering layers comprising solid cushioning material and a casing containing said cushioning material, and being separately tufted and
- an inflatable, flexible foldable first pneumatic cushioning layer,
- said pneumatic layer comprising an inflatable casing,
- said casing providing means to facilitate substantially continuous folding along a plurality of first parallel axes when said pneumatic layer is inflated,
- said pneumatic layer being captured between said opposing covering layers and a second pneumatic layer captured between said opposing covering layers and arranged to be co-planer with said first pneumatic layer, and said futon provides means to facilitate folding along a second axis perpendicular to said first axes.

A flexible, foldable futon, comprising
- opposing flexible, foldable, covering layers,
- at least one of said covering layers comprising solid cushioning material and a casing containing said cushioning material, and
- first and second inflatable, flexible, foldable pneumatic cushioning layers,
- each said pneumatic layer comprising an inflatable casing,
- said inflatable casing providing means to facilitate folding along a plurality of parallel axes when said pneumatic layer is inflated, whereby said futon is foldable along a plurality of parallel axes when said pneumatic layer is inflated,
- said first and second pneumatic layers being captured between said opposing covering layers and arranged to be co-planar, and said futon provides means to facilitate folding along a second axis perpendicular to said first axis,
- in which said first pneumatic layer includes a first means for inflating said first pneumatic layer, and said second pneumatic layer includes a second means for inflating said second pneumatic layer independently of said first inflating means.
