Product Description

The turn times available are 10, 20, 30 and 60 minutes with options to turn right or left only as well as both sides.

Invacare microAIR Lateral Rotation Mattress provides pressure relief and moisture maintenance for patients who need to be turned for pressure relief or other health indications. Inherent in the design of the patented z-cell design is alternating pressure as the mattress turns. This therapeutic system offers relief for pressure ulcers from stages I through IV.

Wireless Auto Fowler to
Prevent Bottoming Out

For the safety and comfort of the patient and caregiver, the microAIR state of the art controller technology monitors the blower and compressor speeds to maintain the appropriate surface pressure once it has been set. Constant air pressure side bolsters help contain patient on the mattress. The MA90Z has a urethane quilted cover to guard against friction and shear.

Another protective measure of the MA90Z Series for patient safety is that the mattress re-centers the patient between rotations. Also, the lateral rotation mode will automatically be stopped when the bed is in the fowler or upright mode.

    The rep at Cascade did what no other healthcare equipment provider did and that was to think out of the box to meet our needs. We got the mattress we needed in days instead of weeks or months. Thank you Mike at Cascade.

    lateral rotation

    Posted by Jonathan Freeman on Apr 25th 2015

    Good air mattress but the lateral rotation doesn't function as advertised. One still has to rely on the help of turning from side to side. To expensive for what it is.

    Does what it says it will do!

    Posted by Ronnie Hutson on Oct 10th 2013

    Weve only owned this for a few weeks, but I think people should know this is doing its job and keeps my fathers skin looking good. I was getting up every night for several months to turn him manually. NOT any more. Its not a regular mattress so you will have to get used to a few adjustments like having the bolster sides do protect him, but it makes the bedspace a tiny bit narrower than the usual width. I can still use sheets if I buy the flannel or jersey, or just get larger sheets that will allow a little space to rotate. I am so grateful for this mattress. I don't see any kind of harm to his skin and this was very hard for me to trust, the 30 degree turn is just fine, too. his skin looks great and this model is quiet. YES quiet. now theres not a bunch of air blowing through it, so if that's what youre hopeing for youll need the other model I believe. ok I said what I wanted to..which was I wish I would have bought it sooner.
