Spex XLella Classic Bariatric Back Support
XLella Classic Bariatric Back Support
Rigid back support with contouring capabilities to shape and configure, for bariatric wheelchair users up to 300kg.
The XLella Classic Back Support is designed to support users with larger pressure distribution who require a back support with the possibility to create shapes and contours for postural support and/or changing needs. The Spex unique contouring cube system can be shaped and configured as many times as needed.
The bariatric population presents specific seating challenges. Positioning the pelvis in neutral may not be possible because excessive soft tissue limits the ability to control the position of the pelvis and spine, therefore, it is essential to provide adequate pressure distribution and relief, heat and moisture control, and ultimately, comfort.
The excessive adipose tissue in the gluteal region (gluteal shelf) can also prevent bariatric users from sitting with adequate spinal support, which can contribute to back pain. Offering solutions to accommodate the unique posterior shape created by this redundant tissue is paramount.
XLella bariatric range consists of back supports and cushions, which span from 22” to 28” width, with options for custom items up to 32”.
The XLella back supports provide an off-the-shelf solution, with integrated adjustability and adaptability for potential changing needs. These are available in three different styles to meet the individual requirements and body shapes of the user, XLella Vigour, XLella Classic, and XLella². All models are transport certified and have a weight capacity of up to 300kg.

Medifab is pleased to provide the most comprehensive special purpose car seat we’ve every introduced for children and teenagers, providing various kinds of extension accessories and multi-adjustable features to allow longer use by the child and to suit the wide spectrum of children’s needs.

For Mild Bony Prominences
Without even adjusting the cube system, the Spex back support has slight contouring and integrates a comfortable pressure reducing foam surface layer to absorb mild bony prominences and asymmetries for uniform torso contact.
For Immersion
For individuals that require immersion into the back support, simply adjust the cube contouring cell system to configure for a perfect fit and shape for the user’s back.
For Asymmetry
For asymmetrical or maladaptive postures, the contour can be arranged to provide the matching shape required to support the user’s torso profile.
