The Axiom SP Visco wheelchair cushion is a game changer in the field of pressure support cushions. It is intended to offer the user with deeper immersion, allowing the trochanters to bear a greater load. This not only increases stability by broadening the base of support, but it also reduces the stress that the tissue supporting the Ischial Tuberosities must bear. The cushion is made out of a thick section of specially designed Viscoelastic foam that deforms to immerse and envelop the Ischial Tuberosities.

This part also has two small places where foam has been removed under the Ischial Tuberosities to allow immersion, as designed anthropometrically. Viscoelastic material is both viscous and elastic, which means it changes shape gradually before returning to its previous shape. This gradual deformation and return to shape enables the cushion to effectively absorb and dissipate energy, resulting in less reaction force pushing back after deformation.

Viscoelastic material:

• It deforms and returns to shape very slowly.
• A viscoelastic material is both viscous (changes shape slowly) and elastic (it returns to its original shape).
• A significant lag is there when viscoelastic foam deforms and when it returns to shape, as energy is effectively absorbed and dissipated.
• During the time lag, there is less reaction force pushing back after deformation.

Increased immersion:

• It allows the trochanters to bear an effective load and provides increases immersion.
• A thick section of specially designed foam deforms to immerse and envelop the Ischial Tuberosities.
• This improves stability by widening the base of support and decreases the load, the tissue that supports the Ischial Tuberosities must bear.

High-quality foam materials:

• The cushion is made up of high-IFD and density.
• High-quality foam materials lead to a comfortable, long-lasting, and high-performing product.
• The dual-density polyurethane foam base gives firm support in the lower layer with a durable comfort layer on top.
• The viscoelastic foam insert with unique hexagonal shapes increases envelopment and decreases compression around the ischia and coccyx.

Surface tension reduction:

• The viscoelastic foam insert with unique hexagonal shapes increases envelopment and reduces compression around the ischia and coccyx.
• The outer cover has a microclimatic spacer fabric layer with a horseshoe design around the well for layer reduction that allows the foam insert to rest directly beneath the pleated 4-way stretch Lycra cover to minimize surface tension.

Pre-contoured shape:

• The well has two small areas where foam is removed under the Ischial Tuberosities to provide immersion.
• The cushion is designed to provide maximum immersion, which allows widening the base of support, the trochanters to bear an effective load, and reducing the load the Ischial Tuberosities must bear.

Feature rich cover:

• The super 4-way stretch Lycra outer cover decreases surface tension.
• There is an easy-to-reach front handle with utility loops for hanging accessories.
• The pleated 4-way stretch inner cover with self-sealing zipper is water-resistant and is easy to clean.
• The water-resistant zipper and loop zipper pull make it simple to don and doff the cover and protect the foam.
