Fitting & Adjustment

User Instructions

Delcaration of Conformity

Fitting and Adjustment Made Simple
The users’ anatomic shape and mass are the only tools needed to ensure a precise and optimal fit. The cushion is designed to react to the weight of the user to dictate the degree of immersion required. As soon as load is equally distributed the adjustment is complete.
Optimised Pressure Distribution & Maximum Stability

The cushion allows the femurs, trochanters, and ischia to all be independently loaded. The fluid under the ischia is specifically engineered to reduce shear strain, while the trochanteric bladders are filled with a stiffer version of Hydrolite for stability when moving and reaching.

Incredibly Light
Axiom’s Hydrolite is incredibly light, eliminating the “weight penalty” of other fluid cushions. Also, it’s less sensitive to temperature, so the fluid performs consistently regardless of how hot or cold the climate.
Superior Microclimate

The cushion base features a dense layer of reticulated foam under a layer of spacer fabric to allow air to flow. The foam base is closed cell and designed with pathways that allow moisture to flow through and away from the body, maintaining a cooler and drier skin interface.

Patented Design

1. Pleated 4-way super stretch Lycra cover to eliminate cover tension
2. Microclimatic spacer fabric layer over reticulated foam comfort layer for air flow
3. Structural Foam Base with Fluid reservoir channels allow for individual adjustment of fluid volume
4. Bilateral Ischial Fluid inserts with more mobile fluid for shear reduction
5. Independent Trochanteric fluid inserts, with stiffer fluid for stability
6. Vents allow the cushion to adjust to changes in ambient pressure

Pre-contoured Shape

Axiom cushions are pre-contoured to facilitate loading the trochanters, decrease ischial loading and improve lateral stability.

Anthropometrics

We cooperated with Georgia Tech to study actual pelvic dimensions and other human measurements. This was critical to designing the cushion’s contours so they properly fit the broad range of users.

Surface Tension Reduction

The ischial bladders rests directly under the outer layer of the cover. By using the super 4-way stretch Lycra outer cover material, surface tension is significantly reduced, providing better immersion.

Frequently Asked Questions

What are the Axiom AS and Axiom ASP wheelchair cushions?

The Axiom AS and Axiom ASP are adjustable fluid wheelchair cushions from Ki Mobility, designed to support skin protection and pressure redistribution. Both use a patented, self-adjusting Hydrolite fluid system that responds to the user’s body weight and shape to help distribute loading. The AS focuses on skin protection, while the ASP combines skin protection with additional positioning features.

How does the Axiom AS and ASP self-adjusting fluid system work?

The cushions contain fluid reservoirs designed to adapt to the user’s anatomy and weight distribution. More mobile fluid inserts beneath the sitting bones help reduce shear, while firmer fluid inserts around the trochanters support stability. The system is designed to adjust fluid volume in response to the user’s body, helping create an appropriate level of immersion and support. Correct fitting and individual assessment remain important.

What is the difference between the Axiom AS and Axiom ASP cushions?

Both models use the same self-adjusting fluid technology, but they have different intended uses and overall heights. The Axiom AS is designed primarily for skin protection and measures approximately 11.4 cm high. The Axiom ASP combines skin protection with additional positioning support and measures approximately 14 cm high. The appropriate model depends on the user’s postural support needs and wheelchair setup.

Can the Axiom AS and ASP cushions help with pressure care?

The AS and ASP are designed to promote immersion, envelopment and pressure redistribution. Their fluid inserts and contoured shapes help distribute loading across the seated surface, while the stretch cover is designed to minimise surface tension. However, no cushion eliminates the risk of pressure injuries. Selection should be guided by an individual assessment and form part of an appropriate pressure-care plan.

What sizes are available for the Axiom AS and ASP cushions?

Both models are available in widths and depths from 14 to 22 inches (approximately 35.6–55.9 cm). The AS measures approximately 11.4 cm in overall height, while the ASP measures approximately 14 cm. Both weigh around 1.5 kg and have a manufacturer-stated maximum user weight of approximately 158.8 kg. The cover features four-way stretch Lycra, with a spacer-fabric layer designed to support airflow and microclimate management.
