Offering high levels of patient comfort, this unique system has the facility to “step up” to that of a dynamic cushion when clinically required. Similarly, the cushion function can be ‘stepped down’ as the patient’s condition improves.


A higher maximum weight capacity, up to 24 stone / 152kg, allows the product to meet the challenges of heavier patients.


The outer cover comprising a high frequency welded, multi stretch and vapour permeable fabric satisfies the strictest infection control policies.


Designed using the latest medical grade cell technology to create greater postural management and pressure relief, this product is specifically made for users considered to be at ‘Very High Risk’ of pressure ulcer development and those with minor postural issues.
