This alternating pressure mattress system offers the therapeutic results and features you would expect in far more expensive systems. The microprocessor allows caregivers to visually monitor the actual pressures in the inflated and deflated air cells 
The SENTRY 1200 AP (Alternating Pressure) Mattress system consists of 20 air cells that, when in the alternating mode alternately inflate and deflate every five minutes.
The alternating pressure relief reduces tissue interface while stimulating peripheral circulation.
Encasing each mattress system is a moisture-proof, vapor permeable coverlet which allows for breathability and comfort while preventing shear and friction.
