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


These features make it particularly beneficial for use within the patient’s home or palliative care environment and help reduce logistic and decontamination costs. The clinical benefits of a single system are equally applicable to those of a modern hospital setting.


A higher maximum weight capacity, up to 40 stone / 254kg, allows the product to meet the challenges of heavier patients.


All component parts are interchangeable and replaceable, maximising product life and reducing environmental impact. The outer cover comprising a high frequency welded, multi stretch and vapour permeable Dartex fabric satisfies the strictest infection control policies.


This product is also available with PU covered umbilical.
