Alternating Pressure Relief Mattresses

Mattresses utilizing alternating pressure therapy, pulsation, or immersive foam air cells are ideal for relieving localized pressure points. Systems with dedicated heel sections, such as sloped foam or specialized cell softening, effectively offload pressure from vulnerable anatomical zones like the heels while redistributing body weight across larger surface areas to safeguard delicate skin.

A pressure relieving mattress is a specialized medical support surface designed to prevent and treat tissue breakdown. Available in non-powered multi-layer foam configurations or powered air systems, these surfaces redistribute interface pressure away from bony prominences. Powered models alternate inflation across air bladders or provide continuous low air loss to manage skin moisture and temperature.

Alternating pressure mattresses inflate and deflate individual air cells in timed cycles, such as 2-in-1 or 3-in-1 sequences. This mechanical alternation regularly relieves pressure under different parts of the body, allowing blood flow to reach compressed skin tissues. By preventing continuous pressure over bony areas, the mattress supports the healing of existing pressure ulcers from stage 1 through stage 4.

Many therapy mattress systems include safety provisions for power interruptions. Features such as cell-in-cell bladders maintain a static column of air to keep patients elevated, while closed-system valves prevent air loss during outages. Other configurations incorporate convoluted foam base layers or foam-in-air cell designs, ensuring uninterrupted support and preventing bottoming out if electrical power is lost.

Low air loss systems introduce controlled airflow across or through the mattress surface to circulate air beneath the patient. When paired with moisture-vapor permeable and fluid-resistant top covers, this continuous air circulation helps dissipate heat and moisture from the patient's skin. Managing moisture and heat maintains skin integrity and creates an optimal environment for wound healing.

Available support surfaces accommodate a broad spectrum of clinical requirements. Standard non-powered foam replacement surfaces typically support user weights up to 350 lbs. Advanced powered alternating pressure and low air loss systems offer expanded weight limits of 440 lbs, 500 lbs, 600 lbs, 700 lbs, and up to 1,000 lbs on specialized bariatric models.
