Spex Ischial
Contour Universal
Positioning Base

Enhanced positioning outcomes underneath air and gel cushions

Traditionally, it has been difficult to meet clinical requirements for wheelchair users with pelvic and postural requirements when seated on pressure care cushions.

The Universal Positioning Base assists with these challenges by insertion under the air/gel cushion to configure the base system as per the user’s clinical assessment, to achieve a functional outcome for the user whilst not compromising with pressure care properties.

The Spacer Universal Positioning Base comes with both an ischial contour base and a pack of 8 contouring obliquity pads. This is ideal for clients who require a pre-ischial ledge that supports the pelvis/thighs and helps prevents the user from shifting forward on the wheelchair cushion. This is especially helpful for user’s with posterior pelvic tilt.

The Universal Positioning Base should be prescribed by a qualified clinician and care needs to be taken that the configuration and position of the UPB components does not jeopardise the user’s pressure requirements.

The Ischial Contour Universal Positioning Base comes standard with…

  • 1x firm EVA foam Ischial Contour Base

Can I sit directly on the Universal Positioning Base?


No, the Universal Positioning Bases must be used underneath a pressure care cushion, such as an air or gel cushion option. They are designed to be used in conjunction with pressure care cushions, to meet postural requirements.
