【Air Circulation Technology】: All the 130 air cells of the alternating pressure mattress inflate and deflate alternately, so that this bed sore pad can distribute the body weight and avoid pressure spots. The constant airflow promotes efficiently the blood circulation and prevent bed sores & ulcers.
【Customizable and Quiet Pump】: The hospital bed mattress has a pressure adjustment button. You can have customizable pumping pressures to suit the needs of people of different weights. It works very quietly (less than 50dB), which can ensure a comfortable, deep and peaceful sleep for the patient.
