Choosing a pressure care mattress is rarely a simple foam-versus-air decision.
Some people need more protection than standard foam can give. Others need a calmer, more familiar surface than a full alternating air mattress. That is where hybrid mattresses come in.
Hybrid mattresses exist to bridge that gap. They combine the comfort and stability of foam with the pressure care benefits of air.
This matters most in care settings where needs can change over time, or where comfort and tolerance matter just as much as therapy. That includes palliative care and progressive conditions, where the surface may need to support skin protection, sleep, comfort, and function all at once.
In the Elata® range, that story comes to life through E400 and E500. Both are hybrids. But they are built for different levels of need.

Why not just choose foam or full alternating air?
Standard foam can be a strong starting point. It is quiet, stable, and familiar. But for some people, it may not provide enough pressure redistribution on its own.
Full alternating air can offer a higher level of therapy. But it can also feel noisier, more active, and less natural for sleep, transfers, or long-term use.
That is the space hybrids are designed to fill.
They are useful when you want:
- more protection than standard foam
- more comfort and stability than full alternating air
- a surface that can better match changing needs over time
In simple terms, a hybrid mattress gives you a middle path.

Reactive and active support: why that matters
Hybrid mattresses make more sense when you understand one key idea.
Some support surfaces are reactive. Others are active.
A reactive surface responds to the person’s body. It moulds around shape and weight to spread pressure more evenly. It does not actively move pressure around on its own.
An active surface changes pressure over time. Alternating air mattresses do this by inflating and deflating different cells in a cycle.
That matters because different people need different things.
- Some need a quiet, stable, reactive surface.
- Some need active therapy because they cannot reposition well.
- Some sit somewhere in the middle.
That is exactly why hybrid mattresses exist.
E400: the quieter, more reactive hybrid option
The E400 sits closer to the reactive side.
It is designed for people who need a calm, stable surface with better pressure care than standard foam, but who may not need a full alternating system straight away.
On its own, E400 works as a static hybrid mattress. That means:
- no pump noise
- no moving cells
- a stable feel for rest and transfers
- more comfort and familiarity in everyday care
This makes E400 a strong fit when:
- pressure risk is low to moderate
- the person has Stage 1–2 pressure injuries
- comfort and sleep are major priorities
- the setting is home care, RACF, or palliative care
- the person has a progressive condition and may need support to step up later
E400 works well when the goal is to protect skin without making the bed feel clinical.
It can also be paired with the EP10AU pump when more support is needed. That gives clinicians a step-up option without changing the mattress itself. This can be especially helpful in progressive conditions, where needs may increase over time and continuity matters.

E500: the more active hybrid option
The E500 moves further toward the active side.
It combines hybrid comfort with alternating therapy, using the EP20AU pump. So while it still offers the feel and support of a hybrid mattress, it adds active pressure redistribution over time.
That makes E500 a better fit when:
- pressure risk is high or very high
- there are more complex Stage 3–4 injuries
- the person cannot reposition well
- a reactive surface is unlikely to be enough on its own
- comfort still matters, even when therapy needs are higher
E500 can also be a strong option in complex palliative care, where clinicians may need more pressure redistribution but still want a surface that feels more stable and familiar than a full air system.
The EP20AU also adds more advanced features, including:
- alternating therapy
- Constant Low Pressure for calmer support when needed
- Elata TiltSense™ for automatic sacral support to prevent bottoming out
- Elata PowerGuard™ battery backup
- Elata SafeHold™ for safe stabilisation during long outages
So E500 is not just “more hybrid”. It is a different level of support.
So why choose a hybrid mattress?
Because not every person needs the same level of pressure care.
A hybrid makes sense when you want to balance:
- protection
- comfort
- stability
- simplicity
- the ability to step care up if needs change
That is the real value of hybrid surfaces. They help avoid two common problems:
- staying on standard foam when it is no longer enough
- jumping straight to full alternating air when it may be too much
Hybrid mattresses are especially useful in palliative care and progressive conditions, where a person’s comfort, function, and pressure care needs may shift over time. They allow support to be matched more gently, without forcing an early jump to a full alternating surface.
Hybrids give clinicians more room to match the surface to the person.
A simple way to think about E400 vs E500
Choose E400 when:
- you want a calm, stable hybrid surface
- comfort and familiarity matter most
- the person needs more than standard foam, but not full alternating therapy
- the care plan may need to step up later
Choose E500 + EP20AU when:
- pressure risk is clearly higher
- active therapy is needed
- you still want the comfort and feel of a hybrid mattress
- you need more advanced support in a complex care setting
So while both are hybrids, they do different jobs:
- E400 = more reactive
- E500 + EP20AU = more active
In one line
Choose a hybrid mattress when you need something between basic foam and full alternating air — and choose E400 or E500 based on how much support the person needs.
Precision in care, built for life.
