Star Stabil-Air

The Star Stabil-Air wheelchair cushion can generally be categorized as an air cushion due to its weight bearing air-filled cells. Star Cushion - the manufacturer of this product - specifies this cushion as follows.

  • Made in Sweden
  • Manufacturer's limited warranty is 2 years
  • The cushion comes with 1 cover
  • The cushion comes with 1 small hand pump
  • Two air cell height options (3 inches and 4 inches)
  • Approximately 4 pounds (varies with size)
  • Optional battery-powered pump/pressure regulator

 Foam Pillar in Air Cell Structure The Stabil-Air name (sometimes erroneously referred to as Stable-Air) is derived from the cushion's foam-in-air structure which produces a less wobbly (i.e., more stable) seating solution than more traditional valved, air-only cushion structures. Unlike the common matrix of equi-pressure air cells, Star's Stabil-Air structure includes a foam pillar inside every air cell. Each foam pillar is shorter in height than the air cell that contains it. The foam pillar geometry varies across the topography of the cushion — the associated variance produces; for example, left and right cushion edges that are more firm than the central portion of the cushion.

 Star Cushion Air Cell Height Options Two air cell heights (i.e., cushion thicknesses) are available. Greater air cell heights generally permit greater immersion in otherwise identical valved air cushions exhibiting the same pressure. However, depending upon how one transfers onto and off of the cushion, greater air cell heights can make transfers more difficult.

The air valve through which the cushion is inflated and deflated, is an easy to use twist-to-open, twist-to-close valve rather than a Schrader type valve.

The extra cover option refers to purchasing a Star Stabil-Air cushion and the extra cover at the same time (not separately).

Star's air cell dimension; in the lateral or horizontal plane, is measured from flap to flap (flap being a base edge of the cell). Specifically: 7 Star cells measure 13½", 8 Star cells measure 15½", 9 Star cells measure 17¼", 10 Star cells measure 19¼", 11 Star cells measure 21", and 12 Star cells measure 22¾". The manufacturer lists the following sizing recommendations.

The cover can be washed in a typical washing machine, but the manufacturer recommends avoiding the use of a washing machine when washing the cushion. The cushion itself can be submerged in a tub or bucket, or otherwise hand-washed using common cleaning agents suitable for clothing. Be sure to close the air valve when washing a Stabil-Air cushion so that the internal foam pillars do not get wet.
