This unique alternating pressure mattress system allows for patients who are at high risk for pressure sores to be placed in a variety of mobile devices. Patients are no longer confined to bed for the whole day due to risks of sitting without proper pressure redistribution. Can be integrated into a geriatric chair, recliner or standard high-back wheelchair. Twenty bladders gently alternate, providing low interface pressures in addition to comfortably supporting the patient. The Chair-Air 9700GR system includes the 9701 alternating pump. Meets California Technical Bulletin #117 for fire retardancy. An optional fire barrier is available to meet the most stringent fire safety requirements, when requested.
