TREZZO HS reactive air™ non-powered hybrid mattress combines the advantages of TREZZO foam technology and 8 FiA™ (Foam in Air) cells with SRA™ (self-regulating air) valves in the torso and leg section, positioned underneath a tri-zonal castellated layer of TREZZO foam. In addition to the immersive benefits of TREZZO foam technology, the FiA™cells with SRA™ valves continuously respond to patient movement optimising body weight displacement and reducing tissue interface pressure. Enhanced air circulation throughout the mattress leads to an even greater reduction in heat and moisture and a further improvement in the patient micro-climate. A number of published Independent Clinical Evaluations have demonstrated that TREZZO foam technology provides an advanced solution for the protection and care of vulnerable patients demonstrating a significant reduction in healthcare costs. TREZZO HS reactive air™ offers an effective solution for pressure ulcer prevention and management for those vulnerable patients who are unable to tolerate a dynamic mattress providing superior comfort. DURA-last™ cover (option) provides added mattress protection for the more challenging healthcare environments. Additional layers provide increased robustness to prevent cover failure due to mechanical or chemical damage increasing mattress life and reducing replacement costs.
