The Science behind Repose Systems

How Repose Works

The New Repose® range is manufactured from the same specialised thermoplastic polyurethane film (TPU), a multi-stretch, moisture vapour permeable material which provides a non-allergenic, soft and smooth user interface minimising friction, reducing shear and consequential tissue damage.

Clinical benefit is provided by a unique combination of 3 key design elements

1. The single cell design

  • One single air cell provides optimal pressure redistribution across the total body contact area.
  • Repose is a reactive mattress, even small movements result in interface pressure being equalised across the entire interface.

2. The material

  • The specialised TPU film is highly conformable and minimises deformation of underlying tissue.
  • The risk of hypoxia and tissue damage is greatly reduced.
  • TPU is moisture vapour permeable reducing the risk of maceration.
  • TPU stretches up to 6 times in every direction for optimum patient support and comfort.
  • TPU provides a soft and smooth user interface minimising friction and shear forces.
 Stretch Material

3. Patented pump & valve technology

  • Patented ‘smart valve’ technology automatically closes when Repose internal pressure reaches 0.2psi.
  • Extensive use has demonstrated 0.2psi to be optimal for pressure redistribution and clinical efficacy.
  • Exhausts excess air for maximum patient support, comfort and clinical benefit
  • Provides reassurance that Repose has not been be over or under-inflated



Why is Repose so extensively used?

Pressure relief is only half the story - pressure redistribution is the key

The conventional static choice:

Static (non-powered) pressure reduction products typically form the first line of defence for patients at risk of developing pressure ulcers and can be gel or air-based but are mainly represented by pressure reducing foam mattresses on beds

The conventional dynamic choice:

Dynamic (powered) pressure relieving products are traditionally perceived as being necessary for high risk patients and for treating those with pre-existing pressure ulcers. The NICE 2003 guidelines stress the value of relatively low cost low technology support surfaces, while noting the lack of evidence for more sophisticated technologies such as APM and specialised beds.


The Repose solution:

Pressure redistribution

An in-expensive system with demonstrable clinical efficacy

In a randomised trial involving 50 patients Osterbrink concluded:

“Repose provides a highly effective system that can be used […] for both preventive and therapeutic purposes.

New Repose® adopts the most natural and effective method of pressure relief and redistribution by reducing the pressure exerted at the interface between the patient and the supporting surface. This is achieved by immersion, maximising the contact surface area and redistributing pressure without compromising surrounding tissue.

Indications for use

Repose products provide effective pressure redistribution for all people at risk of developing pressure ulcers, including those assessed as very high risk.  Repose is also appropriate for users with pressure related tissue damage - clinical supervision is advised where the damage is severe. In-Line with the NPUAP_EPUAP Pressure Ulcer Treatment Guidelines 2009.

Limitations for use

Repose is not suitable for the following:

  • Persons weighing in excess of 139kg
  • Persons with unstable spinal fractures
  • Where body shape is such that the person cannot be fully supported by the Repose mattress overlay or cushion

Repose is suitable for use with bed and trolley side rails subject to the bed or trolley manufacturer’s instructions and appropriate risk assessment


  • If deterioration in skin condition is noted, clinical advice should be sought and, if so advised, use of the product discontinued.
  • Avoid direct contact with heat and sharp objects
  • When deflated, keep away from babies and small children. Keep away from pets.
