Invacare microAIR® MA600 — 3-in-1 Alternating Pressure Low Air Loss Mattress, HeelSense, Max Inflate, 500 lb, Stage I–IV Support

3-in-1 cycle. Two-thirds of the body always supported. Built-in heel protection. The Invacare microAIR® MA600 is an alternating pressure low air loss mattress system designed for the prevention and treatment of pressure injuries from medium-to-high risk through Stage I–IV wounds. Its defining mechanism is the 3-in-1 alternating pressure cycle: cells are grouped into sets of three, and at any given moment only one of every three cells is deflated while the other two remain inflated and supporting the patient. This ensures two-thirds of the patient's body surface is supported at all times — a meaningful clinical distinction from simple A-B alternating systems that can leave up to half the body unsupported during a cycle. HeelSense technology ergonomically curves the foot end of the mattress, naturally cradling the heels without creating new pressure points — addressing one of the highest-risk anatomical locations for pressure injury. Max Inflate Mode rapidly firms the entire mattress surface on demand, providing a stable platform for safe patient transfers or clinical assessments. The air-cells-within-air-cells design means an inner cell stays pressurized even during a power outage, preventing the patient from bottoming out in the center of the mattress. Cells are constructed from soft nylon urethane for comfortable, easy-to-clean, bacteria-resistant performance. 500 lb capacity. Available as mattress only, pump only, or a complete system.

Key Features

3-in-1 Alternating Pressure Cycle

The MA600's defining mechanism groups the air cells into sets of three and cycles them so that only one cell in each group of three deflates at any given time — the other two remain fully inflated and supporting the patient. This is a meaningful design distinction from standard 2-cell A-B alternating systems, where up to half the patient's body can be unsupported at once during the cycle. The MA600's 3:1 ratio ensures two-thirds of the body is always actively supported, providing more consistent overall support while still delivering the periodic pressure relief that makes alternating pressure therapy effective for active wound treatment.

HeelSense Technology

Heels are among the highest-risk locations for pressure injury development — minimal soft tissue coverage over the calcaneus bone means even moderate sustained pressure can quickly compromise circulation to the area. HeelSense technology addresses this with an ergonomically curved foot end design that naturally cradles the heel's shape, distributing contact pressure across a broader area rather than concentrating it directly under the heel's most prominent point. This design works in support of the alternating pressure cycle to provide more complete protection at this critical anatomical location.

Max Inflate Mode

Max Inflate Mode rapidly inflates all cells to create a firm, stable mattress surface on demand — essential for safe patient transfers, repositioning, or clinical assessments where a soft, actively cycling surface would create instability. Rather than requiring the caregiver to wait for the normal cycle to complete or manually adjust multiple settings, Max Inflate provides a single-action solution to quickly prepare the mattress for these situations.

Air-Cells-Within-Air-Cells — Power Outage Protection

Each therapy cell on the MA600 contains an inner cell that maintains its own air pressure independently of the pump's active cycling — meaning that even during a power outage, the inner cells keep the mattress from completely bottoming out in the center where the patient's body weight is concentrated. This nested cell design provides a meaningful safety margin compared to single-layer cell systems that can fully deflate without continuous power.

Soft Nylon Urethane Cell Construction

The therapy cells are made from soft nylon urethane material chosen specifically to reduce shear forces against the patient's skin, simplify cleaning between uses, and resist bacterial growth on the cell surface — all important considerations for a surface in direct, extended contact with patients at risk of skin breakdown or with active wounds.

Who This Mattress Is For

• Patients at medium to high risk of pressure injury requiring active alternating pressure prevention therapy
• Patients with existing Stage I through Stage IV pressure ulcers requiring dynamic wound healing support
• Patients with heel-specific pressure injury risk where HeelSense's curved design provides additional targeted protection
• Patients up to 500 lbs requiring standard-width bed frame compatibility
• Caregivers and facilities needing the flexibility to replace just the mattress or just the pump rather than purchasing a full new system
• Home care and acute care environments seeking a reliable, entry-tier alternating pressure low air loss system
