Pressure Relief Mattress Overlays

A pressure reducing mattress or support surface redistributes body weight to mitigate interface pressure over bony prominences. These surfaces are designed to support patients at risk of tissue injury by providing continuous pressure redistribution, moisture control, and targeted relief to areas prone to skin breakdown, including heels and sacral areas.

An alternating pressure mattress overlay utilizes powered air cells that sequentially inflate and deflate to constantly change pressure points beneath a patient. In contrast, low air loss overlays provide continuous airflow to maintain immersion, dissipate skin moisture, and manage the microclimate for individuals placed at risk of skin ulceration.

An overlay on a hospital bed is a supplemental therapeutic surface placed directly over the standard facility mattress. It enhances clinical efficacy by providing specialized support such as low air loss therapy, microclimate management, and removable heel floatation sections without requiring the replacement of the entire primary bed mattress.

Weight capacities vary depending on the specific model. For instance, the MOXI Hybrid Select Air Low Air Loss Mattress System supports a user weight limit of 300 lbs (136 Kg) while delivering dedicated microclimate management and pressure prevention.

Low air loss systems facilitate continuous air circulation beneath the patient. This targeted airflow manages the skin microclimate by dissipating heat and humidity. Regulating skin moisture reduces friction and shear risks, providing vital support for patients categorized as at-risk for pressure ulcers.

Yes. Advanced overlay systems include removable components, such as the Heal Float feature in the MOXI Hybrid Select Air, which protects heels in bed and can be transferred to seating surfaces for uninterrupted skin protection across patient environments.
