Spex Trunk Supports for Wheelchairs

A stable and correct seated posture is essential for comfort, function, and overall health in wheelchair users. When the upper body lacks adequate support, it can affect balance, breathing, and the ability to use the arms and hands effectively. That is why trunk supports are often a key component of an individual seating solution.
Spex trunk supports are designed to provide targeted support to the upper body and help stabilize the user’s sitting position in the wheelchair. The system allows support to be positioned precisely where it is needed—without unnecessarily restricting freedom of movement.
The Spex system is modular and can be adapted to a wide range of needs. This means the solution can be individually adjusted for both children and adults with simple or more complex seating requirements.

What are Spex trunk supports?

Spex trunk supports—also known as lateral trunk supports—are used to stabilize the upper body and help the user maintain a correct sitting posture in the wheelchair.
The system typically consists of:

• an adjustable lateral bracket mounted to the wheelchair backrest

• an anatomical side pad that provides comfortable support to the body

• multiple adjustment options to ensure an individual fit

This combination enables therapists to position the support precisely according to the user’s posture and needs.

Benefits of the Spex trunk support system

The Spex system is developed for clinical use, where both flexibility and stability are essential.
Key benefits include:

• modular system with multiple configuration options

• precise adjustment of side pads

• stable upper body support

• optional swing-away function for transfers

• a wide range of pad shapes and sizes

• suitable for both symmetrical and asymmetrical seating positions

Spex Axial lateral brackets

Spex Axial brackets are designed to provide a high level of flexibility in positioning the trunk support. The bracket can be adjusted in multiple directions, allowing the side pad to be positioned accurately in relation to the user’s body.
Some models feature a swing-away function, making it possible to move the support away during transfers or when free access to the wheelchair is needed.
The brackets can be combined with different types of Spex side pads, offering great flexibility in setup.

Spex side pads

Spex side pads are designed to provide comfortable upper body support while ensuring effective pressure distribution.
The pads are available in several designs to match individual user needs:

Narrow range

• suitable for smaller body types

• provides precise support close to the body

Wide range

• larger support surface

• increased upper body stability

Bi-angular pads

• developed for more complex seating needs

• provide support at multiple angles

All pads are made with pressure-distributing foam and come with removable covers.

Applications

Spex trunk supports are typically used for users who require additional upper body support in the wheelchair.
The system can be applied in cases such as:

• reduced trunk control

• asymmetrical seating posture

• need for upper body stabilization

• neurological conditions

• complex wheelchair seating requirements

Modular system

One of the key strengths of Spex trunk supports is the modular design.
Brackets and side pads can be combined in many ways, allowing the solution to be tailored precisely to the individual user. At the same time, the system makes it possible to continuously adjust the setup as the user’s needs change over time.
