Technical details
SEAT SYSTEM
SitRite & SitRite LS
The inherent benefits of SitRite are concealed within the seat, taking the form of two foam materials of different densities. The lower, harder foam section helps to hold the pelvis in a good position, while the upper, softer foam section distributes pressure by being thicker under the ischium than it is under the thighs.
SitRite’s back is ergonomically designed, ensuring that a large part of the trunk is supported without impairing arm freedom of movement. The SitRite LS (Lateral Support) variant features a more enclosed back.
SitRite LS has been produced specifically for people with trunk muscle weakness and correctable scoliosis. The enclosing sides are structured around polyester covered plates that can be adjusted whilst the user is in the sitting position.
Both SitRite and SitRite LS can be fitted with a lumbar pillow to provide extra support.
The upholstery is covered by high durable black fabric.
