  • Clinical Justification for OSKA Aria

A person with a disability will have many factors contributing to their risk of developing pressure injuries. We recommend completing an assessment tool to guide the process of identifying the level of risk (have a look at the Purpose T very easy to use tool). This will be a leading factor to guide your equipment prescription and decision making for the most appropriate mattress for the person. (no Risk, Low Risk, High Risk, Very High Risk, Category 1/2 , Category 3/4 /Unstageable). For a person up to category 3 of pressure injury or category 4 injury on the heels the OSKA ARIA would be a suitable option due to:


Pressure Care: to treat or prevent pressure areas from developing.

Features of the OSKA ARIA mattress for the prevention or treatment of pressure injuries include:

  • Anti Shear Design

    Pressure injuries occur due to a combination of pressure and shear on an area of the body. The design of the mattress reduces the risk of shear on the body as the base foam of the mattress remains in position on the bed frame, the top moves with the user, to reduce friction and pressure damage.

  • Pumpless Self-Adjusting Air Mattress

    Suitable for prevention and treatment of pressure damage up to and including category 2 (where the patient is compliant and regular repositioning is taking place category 3 wounds can also be treated). Self-alternating cells down the centre of the mattress offer considerably better pressure redistribution. The cells continually adjust to the patients ’s body weight and motion, presenting high level of pressure care and therefore allowing for pressure redistribution in the right areas of the body.

  • Aerolite Foam

    This technology has been designed to allow air to flow through the foam to ensure the body stays cool and dry. The microclimate properties of this foam are vital, as the body maintains a cooler temperature, this prevents sweating and notably reduces the occurrence of pressure injuries.

  • Heel Relief Slope

    The heel relief slope is an exceptional feature in reducing the risk of pressure wounds on the heel, caused by friction and/or disproportionate weight distribution through the heel rather than the calf. The calf has significantly more surface area than the heel allowing pressure to distribute over a larger area reducing the risk of pressure build up. It is important to note that the heel slope length and angle on the OSKA products have been carefully designed to accommodate most patient heights (leg lengths) for most appropriate placement of the heel slope to the person’s body. If the slope angle is incorrect it can result in excess pressure on the heel from weight being distributed down the leg.


    The OFFLOADER™ is appropriate in the use of preventing and treating heel wounds up to and including category 4. The OFFLOADERTM can be adjusted to each user ensuring correct positioning. It is to be used for those with category 3 or 4 heel wounds. The OFFLOADER™ function can be used to suspend the heel for ‘zero pressure’ and increases the blood flow to the heels, which reduces the risk of the development of pressure wounds. The OFFLOADER™ is also valuable in assisting nursing staff in providing inspection, cleaning, dressing and care in the area.

  • Vapour permeable material

    This bi-elastic PU/polyester coating reduces the risk of developing pressure damage through allowing interface movement which helps lower the risk of shear damage, friction and disperse moisture.

Transfers: to allow a person to easily transfer in and out of bed or to promote independent repositioning and movement.

A large factor of prescribing a pressure mattress is ensuring a person will manage their transfer/movement in bed with the mattress provided. By providing a mattress that treats their pressure injury we do not want to be inhibiting them from movement/transfers as is often the case.

The OSKA ARIA features which promote safe/easy/independent movement and transfers include:

  • Firm Supportive Sides

    The supportive foam edges supply accelerated balance and comfort for the consumer. That is critical for transfers on and away from bed, making an allowance for simpler mobility. The firmer surround additionally facilitates to lessen disorientation through supplying further guide and stability whilst sitting or getting off the edge of the mattress.

Comfort: to provide a person with the ability to sleep and rest comfortably in bed to encourage participating and engagement in daily activities.

If a person is not comfortable on the mattress provided, they will likely not comply with using the product. But more importantly a person uncomfortable on their mattress can have many long lasting detrimental effects on their health and wellbeing – reduced sleep, longer time in bed, contributing to higher level of pressure risk, reduce mobility, poor participation in valued roles and activities.

The OSKA ALTO has been designed to incorporate a high level of comfort through the use of the following features:

  • 4 star comfort rating

  • Pumpless

    The non alternating air feature of the ARIA which continues to provide a high level of pressure care is often an appropriate option for people who find an alternating air mattress uncomfortable and clinically can tolerate this firmer form of pressure relief.

Size and Shape: to allow the option of sizes for a wide range of different users and differing types of bed.

The mattress provided to a client needs to be compatible with that persons weight, height and their environment I.e. type of bed.

The OSKA ARIA is compatible with:

  • Single Options

    Standard - 88x200x18cm Bariatric - 107x200x18cm

  • Weight capacity

    Max user weight of 230kg

  • Standard or profiling bed

Maintenance: easy maintenance of the bed assists in assuring a client and their carers of the effectiveness of the product and helps reduce future costs in longevity of the product.

Important factors when considering the correct mattress for a person is how easily the product can be used/maintained for safe and efficient use.

The following maintenance features of the OSKA ALTO contributing to the long-lasting nature of the product.

  • Easy to clean and chemical resistant

    The material of the mattress cover withstands aggressive cleaning regime which helps maintain a high level of infection control and which extends the life compared to traditional materials. Washable to 95 degrees Celsius.

  • Welded seems

    The design stops the spread of infection at home, hospital or care setting as there are no holes or gaps for bacteria to get into. This also reduces the possibility of moisture (i,e, incontinence) seeping into the centre of the mattress.

  • Waterfall Flap

    The mattress is concealed by fluid resistant extra-long waterfall flap and when opened, gives access to confirm that fluids have not permeated the cover and damaged the foam. Inspection control is maintained for handles.

  • Crib 5 fire rating

    High fire rating score makes this a suitable option to ensure safety of clients, especially those at risk of fire outbreaks i.e. use of oxygen.

  • Fire Evacuation Base

    In case of emergency, the whole mattress and user can be transported using straps and handles integrated into the design of the mattress. Ideal for use in hospital or aged care settings.

  • Non Powered

    As there is no use of electricity and no pump to function, the OSKA hybrid is extremely easy to use. This is an easy solution for carers as they are not spending time operating a pump. The sound of silence is also essential to the sleep quality of most people. Contributes to affordability, making this mattress a cost-effective solution which is also low maintenance so suitable in more rural areas.
