Hydrolite fluid bladder
Supports the Ischial Tuberosities

The Axiom SP Fluid uses a Hydrolite fluid bladder instead of Viscoelastic Foam. The bladder rests directly under the super stretch outer cover, allowing it to conform to the tissues supporting the Ischial Tuberosities.
Hydrolite is a non-Newtonian fluid that behaves as a solid under the force of gravity, but flows as a viscous fluid under load, which can help minimize shear. It is also incredibly light, eliminating the “weight penalty” of other fluid cushions. It is less temperature sensitive than other fluids, meaning it will provide more consistent performance regardless of climate.

Frequently Asked Questions
What is the Axiom SP Fluid wheelchair cushion?
The Axiom SP Fluid is a skin protection and positioning cushion from Ki Mobility, designed to provide immersion, envelopment and support. It combines a dual-density foam base with a Hydrolite fluid bladder positioned beneath a four-way stretch outer cover. This design helps the cushion conform to the user’s seated anatomy while supporting pressure redistribution and positioning.
How does the Hydrolite fluid bladder work?
The Hydrolite bladder sits directly beneath the cushion’s stretch outer cover and conforms to the tissues supporting the user’s sitting bones. The fluid can move under load, helping the cushion adapt to the user’s shape and reduce surface tension. Combined with the pre-contoured foam base, this is designed to improve immersion and distribute loading across a broader support area.
Can the Axiom SP Fluid cushion help with pressure care?
The Axiom SP Fluid is designed for skin protection and positioning. Its fluid bladder, contoured foam base and stretch cover work together to promote immersion and envelopment, helping redistribute pressure while supporting pelvic stability. No cushion eliminates the risk of pressure injuries, so selection should be based on an individual assessment and form part of an appropriate pressure-care plan.
What is the difference between the Axiom SP Fluid and Axiom SP Visco cushions?
Both cushions are designed for skin protection and positioning and share a contoured, dual-density foam base. The main difference is the insert: the SP Fluid uses a Hydrolite fluid bladder, while the SP Visco uses viscoelastic foam. The choice depends on the user’s needs and the seating professional’s assessment of the required immersion, envelopment and support characteristics.
What sizes and cover options are available for the Axiom SP Fluid?
The Axiom SP Fluid is available in widths and depths from 14 to 22 inches, with an overall height of approximately 11.4 cm and a weight of approximately 1.6 kg. The standard cover uses four-way stretch Lycra, while an optional wipeable, incontinence-resistant cover is available. The manufacturer’s listed maximum user weight is approximately 159 kg. Confirm the required dimensions and current options before ordering.
