Spex Zygo Deep Contour Mid Back Support
Zygo Deep Contour Mid Back Support
Enabling freedom without compromising posture and comfort, Zygo is a back support with inbuilt laterals designed for full-time self-propelling wheelchair users.
Active wheelchair users don’t want to be held back – they want the freedom to go places and do amazing things.
Zygo back support systems are lightweight, easily adjustable, easy to install and remove, more breathable and more personalised.
Zygo back support systems give you more comfort, flexibility, personalisation, and freedom to move – enabling you to go places, achieve more, and be whoever you want to be.
The back support is an integral wheelchair component for appropriate seating position and trunk support. It plays an important role in increasing comfort and function for wheelchair users.
Sitting over extended periods of time can cause discomfort and accelerate the development of spinal deformities. Manual wheelchairs are usually supplied with sling-style back supports which do not provide appropriate postural support, nor adequate pressure relief, for some full-time wheelchair users. Rigid back supports are recommended for improved postural support and comfort.
Spex Seating aimed to design the Zygo back supports with suitable shapes and sizes for most active users, without any major adjustments or customisations.
A mid height shell with a supportive deep contour provides…
- Support for the pelvis, lumbar spine and thoracic spine
- Deep contour suitable for users with limited trunk mobility and strength
- Different height options allow the shell to reach the mid-thoracic or upper-thoracic region
Functional benefits
Fits to You, Not Just to the Chair
When it comes to finding the right size and style, the Zygo fits to the user not just to the chair!
User-focused scripting – by user size, not wheelchair width ensures a tailored fit to the torso.
Extensive range of size and style combinations available from two shell contours (Active and Deep) and varying shell heights (Lo and Mid).
Aesthetic and Minimalistic
Look your best with Zygo! From the perfectly contoured shape, to the futuristic and tasteful ventilated shell pattern, achieve effortless style and class through the Zygo’s elegant design! The Zygo lets you be your true self. All Zygo back supports are supplied with a cover extension.
Compatibility With Different Wheelchairs
Unique breathable shell design allows interfacing of the shell to a range of different wheelchair styles, from lightweight manual chairs to complex power chairs. The carefully placed hole cut-outs allows the shell to be directly mounted to certain wheelchair frames and is also compatible with central mounting systems.
Easy to Use and Easy to Adjust
From installation through to adjustment the Zygo has been designed to be easily adjustable, easy to use, and easy to remove. Suited to those with limited hand function, the easy ‘drop-in’ installation is made possible by the lightweight quick-release Drop Mount Hardware. The invertible shell design (on mid-height back supports) provides easy adjustment of the lateral height to achieve optimum trunk stability, enable a precisely tailored fit and accommodate postural and growth requirements. Removable and washable cover design.
