What is the difference between the Series3 Auto and Series3 Eco mattress?

The OSKA Series3 Auto and OSKA Series3 Eco are both alternating air, full replacement pressure care mattresses designed for pressure ulcer prevention and treatment, but the key difference is the pump technology and level of automation.

Main differences

Feature	OSKA Series3 Auto	OSKA Series3 Eco
Pump type	Automatic Auto-Weigh pump adjusts pressures automatically based on patient weight.	Manual/Economy pump requiring caregiver adjustment.
User error risk	Lower, because the pump automatically sets support levels.	Higher, as settings must be selected manually.
Nursing time	Reduced due to automatic weight sensing.	More staff intervention required.
Clinical environment	Well suited to higher-acuity settings where patient weights and conditions change frequently.	Often chosen where a simpler, lower-cost solution is sufficient.

What they have in common

The Series3 Auto and Series3 Eco are both intended for:

Prevention of pressure damage for very high-risk patients.
Treatment support up to Category 4 pressure ulcers (with clinical assessment).
Full replacement alternating air therapy.
Cell-on-cell construction to reduce bottoming out.
CPR deflation function.
Profiling bed compatibility.

In practical terms

Choose Series3 Auto if you want the mattress to automatically calculate and maintain the correct pressure settings, reducing nursing workload and minimising setup errors.
Choose Series3 Eco if cost is a bigger consideration and staff are comfortable manually setting and monitoring the mattress pressures.

The Auto model is generally regarded as the more advanced option because of its automatic weight-adjustment technology.
