Like the Axiom SP Visco, the Axiom SP Fluid is designed to provide increased immersion, allowing the trochanters to bear an effective load, widening the base of support, and reducing the load the Ischial Tuberosities must bear. 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.

Fluid functions very differently than foam. While foam must compress and has elastic characteristics, fluid displaces. It actually moves away from a shape and tries to create an equilibrium where all the areas in contact with the shape have equal loading. 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.

Super 4-way stretch Lycra outer cover material reduces surface tension.

Outer cover features a spacer fabric layer with a horseshoe design, providing microclimatic airflow along with layer reduction over the Hydrolite ® fluid bladder.

The Hydrolite ® fluid bladder is designed to sit on top of the waterproof inner cover; reducing surface tension and maximizing envelopment of the ischia and coccyx.

Dual-density polyurethane foam base offers firm support in the lower layer with a durable comfort layer on top.
