A solution for complex support needs

The Octoback is a comfortable specialist backrest offering adjustable support for the pelvis and spine. As users grow and skeletal changes occur, the Octoback can be easily modified to accommodate evolving requirements.

The Octoback provides support for complex needs, as well as pelvic obliquity and scoliosis. It fits all Chunc chairs and is cross-compatible with many other brands too.

Localised support

The Octoback is made to meet each individual’s specific needs and is built with three to seven lateral segments.  Each of these segments is positioned independently to offer localised support for the pelvis, lumbar and thoracic spine. The segments can be easily adjusted in response to growth, weight gain or loss as well as skeletal changes that occur over time.

In detail

Octoback creates a pelvic girdle, which can be extended to provide thigh laterals to manage adduction and adjusted to the seat width required. Thoracic level support is offered with width adjustment easily set.

Compatible backrest

Octoback fits every chair in the Chunc range and is also compatible with a large number of other wheelchairs, mobility bases and specialist seating options.

Chunc chairs are robust and so easy to adapt. This means we as an outdoor centre can enable hundreds of guests to access the outdoors. It grows with the person which means that almost all guests no matter what their size or shape can be made comfortable.  Thank you to Chunc for kindly supporting The Bendrigg Trust and all of our guests in delivering epic memory-making experiences in the great outdoors.

The new Chunc One wheelchair base with its sleek design and colours of black and red is very attractive. Its shock absorbing properties are par excellence, especially for users who like motion. Together with its wide wheels with deep tread, this makes for ease of pushing for the attendant – especially on uneven surfaces and rough terrain.

Faustina Turner, Physiotherapist

My daughter has complex needs and our seating specialist Terry went the extra mile to make the entire process as stress-free as possible. From start to finish, he took ownership, and could not have been more accommodating and flexible. Terry could not have been more helpful, professional and understanding.

For families in our position that is incredibly helpful and very much appreciated.


Mr Mcleish, Parent

What we have really appreciated over our years with Chunc, is that they accommodate our needs. Our daughter’s condition is ongoing so we are often in touch with our Seating Specialist, Morgan, and he is always obliging and attends meetings with ourselves and our OT. It means a great deal to us that we can have an on-going relationship with the Chunc team.

J Weaver, Parent

We have been Chunc customers for the past seven years. Both daughters have them and recently have moved to moulded seats. We have found them both attractive and robust. Although a little expensive initially their longevity makes them a cost effective option. Our seating specialist, Ian Park, has always been friendly and knowledgeable providing excellent service, even travelling to our holiday destination to repair a gas strut after an emergency breakdown. I highly recommend Chunc.
