The True³ Digital Mattress System sequentially reduces pressure to zero across the whole body every 7.5 minutes — active pressure relief that works whether or not the patient can be repositioned.
Most support surfaces (low air loss, air fluidized) are immersion technologies: they reduce pressure by sinking the patient into the surface. Pressure is redistributed, but it stays constant unless the patient is moved — and it is never reduced to zero.
The True³ Digital System is an active surface. It cyclically alternates a series of three cells so the patient rests on the bed in natural spinal and pelvic alignment — relieving back, hip, and neck pain and improving compliance — while the surface does the offloading automatically.
How TRI-PHASIC works →
Whole-body pressure is reduced to zero every 7.5 minutes — independent of patient movement or position.
The rolling A–B–C pressure cycle promotes capillary micro-bursts to maximize blood and lymphatic flow.
A dedicated row of cells with a one-way valve keeps the patient supported even through power loss or pump failure.
No powerful fan blowing air across the patient — quieter sleep, no added heat to the room, infection-control by design.
Strap down the mattress, attach the pump, plug in. No special linens or expensive breathable pads needed.
Standard hospital-bed and bariatric sizes, with replacement covers, mattresses, and pumps available.
Pressure ulcers in subdermal tissue under bony prominences can begin within the first hour to 4–6 hours of sustained loading. Guidelines call for offloading cycles several times each hour to reduce the risk of ischemia-reperfusion injury.
"Active surfaces, by the very nature of their design, periodically off-load the tissue, meaning that they are considered the modality of choice for patients who cannot be regularly repositioned."
