Spex XLella2 Bariatric Back Support
XLella2 Bariatric Back Support
A biangular back support with two adjustable sections to accommodate gluteal shelf and excess adipose tissue, for bariatric wheelchair users up to 300kg.
The XLella² provides a higher degree of trunk support by offloading the posterior side of the pelvis to accommodate a gluteal shelf. Its lower section has a total of 85⁰ of adjustment, with 55⁰ posterior and 30⁰ anterior. This maximises pressure distribution and relief, to assure adequate postural support, and ultimately provide comfort.
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.
