Air Overlay Mattress For Single Bed Alternating Pressure Pump

Description

Alternating Pressure Air Overlay Mattress NZ — Pressure Care for Bed Sores

An alternating pressure air overlay mattress is a pressure-care support surface that sits on top of an existing mattress and gently changes the points of contact with the body. Its air cells slowly inflate and deflate in a cycle, redistributing pressure and supporting blood flow to the skin — which helps reduce the risk of pressure injuries (bedsores) for people who spend long periods in bed.

Often searched as an air mattress for bed sores, alternating pressure mattress, pressure relieving overlay or orthopedic air mattress, it’s a practical, affordable layer of protection for home, hospital and aged-care use.

How It Works

The overlay is made up of air-filled cells that inflate and deflate in sequence, so the pressure points under the body are constantly changing rather than staying in one place. This intermittent relief supports circulation to the skin and is a well-established way to help prevent and manage pressure injuries, used alongside regular repositioning and professional advice. The cycle time and firmness are adjustable so you can set a comfortable, effective pressure for the user.

• Sits on your existing bed — a simple overlay, no need to replace the mattress
• Quiet pump — around 40dB for restful sleep
• Suitable for home, hospital and aged care
• Free NZ-wide delivery with a 12-month manufacturer warranty

Who It’s For

An alternating pressure overlay is designed for anyone at risk of, or already managing, pressure injuries — typically people who are bed-bound or spend long periods in bed with limited ability to reposition themselves. It’s widely used in home care, hospitals and aged-care facilities, and during recovery or rehabilitation. Because everyone’s skin and pressure-care needs are different, we recommend a health professional (such as a nurse or occupational therapist) is consulted when choosing a pressure-care product.

Important — Monitoring & “Bottoming Out”

All pressure-care products should be monitored to prevent “bottoming out” — where the user’s weight compresses the surface so far that the bony parts press against the base below. If this happens even with correct use (for example, correct inflation), a different product may be needed. An overlay isn’t suitable for everyone; it may not suit children or during pregnancy, so check with a health professional if you’re unsure.

Using It with Other Beds & Mattresses

The overlay can be used on top of standard foam, memory foam, gel or bamboo mattresses, as well as on our adjustable and hospital beds. For a full replacement pressure mattress rather than an overlay, see our anti-bedsore air mattress.

How to Set It Up

1. Lay the overlay flat on top of the existing mattress
2. Connect the air hose to the pump unit and to the overlay
3. Turn on the power and switch on the pump
4. Let it inflate, turning the pressure adjustment up to begin
5. Once inflated enough to support the user in bed, adjust down to a comfortable pressure

Frequently Asked Questions

How does an alternating pressure overlay help with bed sores?

By continuously changing the points of contact between the body and the surface, it reduces how long any one area is under pressure and supports circulation to the skin. This helps reduce the risk of pressure injuries developing. It’s used alongside regular repositioning and professional guidance, not as a replacement for them.

What’s the difference between an overlay and a full pressure mattress?

An overlay sits on top of an existing mattress and is a lower-cost option for lighter needs. A full replacement pressure mattress takes the place of the normal mattress and suits higher-risk users who spend more time in bed. If you’re unsure which is right, contact our team.

Can I use it every night?

Yes, it’s designed for continuous everyday use while sleeping. It may not be suitable for everyone, including children or during pregnancy — check with a health professional if you’re unsure.

What weight can it support?

The overlay supports a maximum load of around 120–130kg. For higher weight capacities, contact us about a bariatric pressure mattress option.

Is the pump noisy?

No. The pump runs at around 40dB, which is quiet enough for restful sleep.

Does it come with a warranty and NZ delivery?

Yes. It ships New Zealand-wide with free delivery and a 12-month manufacturer warranty, with remote phone and email support.
