Cavitator Support Surfaces

The Cavitator line refers to a category of low-air-loss and alternating-pressure support surfaces built around a "cavitated" foam or air-cell design, engineered to help prevent and manage pressure injuries in patients with limited mobility. If you're outfitting a long-term care facility, a home hospital bed, or a bariatric setup, the questions that matter here are the same ones we hear most: how does the surface redistribute pressure, will it fit the existing bed frame, and what level of skin risk does it address?

Cavitator mattresses and overlays work by distributing body weight across a contoured surface so that no single area bears sustained pressure long enough to compromise circulation. Low-air-loss variants add a steady flow of air through the surface to manage moisture and heat against the skin — an important factor for patients prone to maceration or those already showing early-stage breakdown. Alternating-pressure models cycle inflation between air cells to actively shift load, which suits higher-risk and Stage III–IV wound situations.

When choosing between an overlay and a full replacement mattress, weight capacity and patient risk level are the deciding factors. Overlays sit atop an existing mattress and work well for prevention and lower-acuity needs; full replacement systems are appropriate for patients requiring therapeutic pressure relief around the clock. Confirm the surface dimensions match your bed frame and that the weight rating covers your patient population before ordering.
