Vicair Adjuster O2

The Vicair Adjuster O2 wheelchair cushion — the manufacturer's replacement for the older Adjuster X model — can generally be categorized as an air cushion due to its weight bearing air-filled cells. The manufacturer of this product, Vicair (in the USA - The Comfort Company is the source) specifies this cushion as follows.

  • Standard thickness is ~4 inches (~10 cm)
  • Low profile thickness is ~2.5 inches (~6 cm)
  • Approximately 2.5 pounds
  • The cushion comes with 1 cover

Vicair's Adjuster O2 consists of a matrix of 5 individually adjustable chambers. Each chamber contains a user-changable quantity of permanently sealed tetrahedron-shaped air cells.

 Air Cells

Vicair accomplishes the weight bearing function differently than other manufacturers of air cushions. The Vicair Adjuster O2 employs many small permanently sealed air filled cells, rather than larger valved air cells. Each of the many small Vicair air cells is shaped like a tetrahedron (a volume enclosed by four sides). The feel of the cushion can be adjusted by unzipping the liner and removing or adding an appropriate number of air cells. A pack of 50 extra air cells may be purchased with the cushion (refer to the cushion options above).

 Tetrahedron-shaped Air Cells

The Adjuster O2's many-cell structure eliminates the leak-related catastrophic failure mode associated with other types of air cushions. The tetrahedron-shaped cell structure also slightly increases the user's seating stability as compared to typical passive, valved-type air cushions.

The O2-series covers include Incotec and Comfair. The Comfair cover is the more breathable of the two covers, the Incotec cover being designed as an incontinence barrier.

NOTE ABOUT SHIPPING: Vicair Adjuster O2 cushions are made-to-order. The manufacturing process typically takes 4-5 business days. For example, if the "Fast" shipping method is selected for a Vicair Adjuster O2, the actual transit time will indeed be fast (1-2 business days), but your cushion may be delayed by 4-5 business days before leaving the facility. Additionally, non-standard sizes (sizes highlighted with colors) require substantially longer lead times. Please consider these manufacturing times when selecting the shipping speed for Vicair cushions.
