The new Stimulite Adjustable Contoured wheelchair cushion can generally be categorized as a honeycomb cushion due to its honeycomb-like structure. Supracor - the manufacturer of this product - provides the following details about this cushion.
Adjustability in firmness is achieved by changing or combining inserts. All three inserts; white, magenta, and gold (from softest to most firm), come with this cushion. Each insert exhibits a firmness that differs from the other two inserts. The sandwich of stackable, user-configurable layers enables the possibility of changing the cushion's support level and immersion to accommodate different situations.
With the XS option and all inserts removed — the softest configuration — this cushion is softer than the original Contoured XS. Thusly configured, the feel of the Stimulite Adjustable Contoured cushion is close to the feel of the soft pink contoured pediatric model.
The geometry of the cushion's top surface — the contouring — is identical to the original, non-adjustable Stimulite Contoured model.
Note that the extra cover option refers to purchasing a Stimulite Adjustable Contoured cushion (with or without other options) and the extra polyester cover at the same time (not separately). The extra sheepskin cover option references real New Zealand sheep skin that stretches in true four way stretch fashion (i.e., the cover stretches in the width direction and in the perpendicular front-to-back direction). The optional water-proof cover fits around the top and sides of the cushion in shower-cap fashion.
If a custom taper, rail, notch, or leg cut is desired, complete and return the Custom Cut Stimulite form. Note that the back two corners are already inset a bit in Supracor's Adjustable Contoured cushion geometry. Also note that custom tapers greater than one inch (the difference between the back and front widths) may adversely affect the Contoured's contouring.
Its perforated, open cell structure permits more air circulation against adjacent buttocks and leg areas than most other types of cushions. The associated air circulation assists in the prevention of skin maceration. Note that the use of a non-porous cushion cover countervails the cushion's advantage with regard to air circulation.
The "XS" option specifies a softer top layer of the honeycomb material. The XS option does not change the thickness (i.e., height) of the cushion. The XS option replaces the top layer of the cushion with a slightly less dense (i.e., slightly softer) layer of honeycomb material.
The manufacturer's 3" thickness specification is; of course, somewhat of an average since the contoured surface of this cushion - its curvy top - exhibits a range of thicknesses that vary from point to point on the cushion. The front, left and right edges of the cushion, and the center pommel, are approximately 3.5" thick. The front leg well areas - the two low areas seen from the front - are approximately 3" thick. The rear seat well area - the back of the cushion where the buttocks would rest - is approximately 2" thick.
The extra one inch thickness option refers to the additional inch being added to the bottom of the cushion, whether or not the cushion has an XS top. Note; however, that the extra one inch thickness cannot be added to cushions with a "Sling" bottom.
An optional half inch thick obliquity pad (or two pads if an inch thickness is needed) can be useful in helping to compensate for hip asymmetry (i.e., a pelvic obliquity).
The Stimulite Adjustable Contoured cushion is suitable for people who must use a wheelchair as a result of a spinal cord injury (e.g., paraplegia, quadriplegia or tetraplegia), stroke, amputation, spina bifida, or other disability.
