Clinical-grade dual therapy in a practical, caregiver-friendly system — alternating pressure continuously relieves stress on vulnerable skin while low air loss keeps the surface cool and dry, helping protect skin integrity around the clock.

The Invacare microAIR MA500 is a well-established alternating pressure and low air loss mattress system designed for patients who need consistent therapeutic support during extended bed rest. It addresses two of the most common contributors to pressure injury development — sustained pressure on bony areas and moisture buildup at the skin surface — in a single integrated system.

Trusted in both home care and clinical settings, the MA500 is built around ease of use without sacrificing therapeutic performance. The adjustable comfort settings allow caregivers to personalise therapy based on patient weight and condition, and the cell-on-cell design provides a safety net during power interruptions — keeping the patient supported even if the pump temporarily loses power.

Who Is This Mattress Best For?

• Patients at moderate to high risk for pressure injuries or skin breakdown
• Patients requiring alternating pressure therapy during extended bed rest

Why Choose the microAIR MA500?

The MA500 has earned its reputation by delivering genuine clinical performance in a system that caregivers can actually manage day to day. Where some advanced therapy systems come with complexity that creates friction in care routines, the MA500 keeps setup and adjustments straightforward — which matters when consistency of use is what drives outcomes.

The combination of alternating pressure and low air loss in one unit means caregivers are not managing two separate systems. The heel pressure relief zone addresses one of the most commonly overlooked pressure injury sites. And the cell-on-cell base removes the risk of bottoming out during a power interruption — a meaningful safety feature for overnight home care use.

For caregivers who need a system they can trust to work reliably without constant adjustment, the MA500 is one of the stronger choices in this category.
