The Invacare microAir Lateral Rotation Mattress offers the benefits Lateral Rotation, Alternating Pressure and On-Demand Low Air Loss. The MA90Z is a deep flotation therapy system that can directly replace specialty hospital beds.

The MA90Z is portable, and readily attached to most hospital and nursing home beds. The MA90Z replaces the mattress on standard medical beds. It provides continuous flotation in all turning modes assuring that patients do not “bottom out” on a hard bed surface. The mattress will maintain the patient on an air flotation surface during a power failure. When power is restored, the system will resume operation without intervention by the care giver.

How it works:
When the mattress is set to a rotate mode the alternating pressure system slowly deflates/inflates air bladders. When not in a rotate mode the air pressure remains the same in all bladders. The MA90Z Low-Air-Loss mode is selected by a front panel button.

User Settable Rotation:
The microAir Lateral Rotation Mattress is capable of turning/rotating the patient up to 30 degrees. The pump system is programmable so you can set or change rotation intervals. Rotation intervals can be set to 10, 20, 30 or 60 minutes with option to turn right or left only or both sides. This eliminates caregivers having to manually re-position the patient through the day or night.

Best for Prevention and Treatment:
The microAIR Lateral Rotation Mattress combines the benefits of Lateral Rotation, Low Air Loss and on-demand Low Air Loss pressure relief in a single portable system. The system's two selectable turning angles provide the ability to bilaterally rotate patients a partial turn. This reduces the risk of complications associated with immobilization. In addition, the MA90Z offers unmatched patient comfort and pressure ulcer management by regulating heat and moisture, relieving pressure and reducing friction and shear. The process is automatic and completely adjustable.

Easy-to-use control panel:
The user-friendly control panel allows the system to be customized to meet individual needs. New features like quick CPR deflate, panel lockout, low pressure alarm, and 24-hour backup help improve patient care. As with all microAIR products, the MA90Z Mattress is easy to install on a standard hospital bed and simple to operate and maintain. In fact, the microAIR Lateral Rotation Mattress by Invacare benefits everyone. It enhances patient care quality and increases caregiver productivity, all at an economical cost.

About Automatic Wireless Mode:
When the bed articulates to 30°, the transmitter in the head of the mattress signals the control unit to increase the pressure in the mattress by 80% to prevent the patient from bottoming out.

Lateral Rotation & Head Elevation:
The MA90Z Mattress will rotate the patient with the head elevated up to 30° (or until the Fowler adjustment kicks in).

Price is for Mattress only, does not include hospital bed.

Mattress requires Side Rails:
The Lateral Rotation Mattress must be used on a medical bed frame with side rails. The side rails must be in the raised position whenever patient is on the bed. Mattress MUST fit bed frame and side rails snugly to prevent patient entrapment.

Key Benefits:
  • Automatic turning and static floatation modes
  • Easy-to-understand, caregiver-friendly membrane control panel
  • Bilaterally turns resident up to 30° at preset intervals
  • Auto-firm feature inflates the mattress to maximum firmness to facilitate resident handling

5 of 5 Turning Mattress March 3, 2018
Reviewer: Joshua W. from Dallas TX  
I bought this for my 88 year old mother who barely weighs 120 pounds. She suffered stroke 2 years ago and we were having to turn her throughout the night because she can't reposition herself. This mattress does it all by itself. We do not need to get up and turn her now. Price was good and delivery no problem.
