Foam vs Alternating-Pressure Mattress in Hospitals: What Evidence Says
Cochrane evidence finds foam alternatives to standard hospital foam reduce pressure ulcers in at-risk people, and the relative merit of alternating and constant low-pressure devices is unclear. Choice is clinical and depends on risk.
Key points
- What the evidence says. A Cochrane review found foam alternatives reduced pressure-ulcer incidence compared with standard hospital foam.
- Practical differences. High-specification foam needs no power and little maintenance.
- Decision. Risk assessment by clinicians decides which surface is used.
- What this means for buyers. Match the surface to the risk group set by clinicians, check bed compatibility and servicing for powered systems, and compare whole-life cost, including pumps, cells and maintenance.
- Detailed guidance. The two options solve different problems and are chosen by clinicians according to risk.
What the evidence says
A Cochrane review found foam alternatives reduced pressure-ulcer incidence compared with standard hospital foam. It found the relative merits of alternating-pressure versus constant low-pressure devices unclear.
Practical differences
High-specification foam needs no power and little maintenance. Alternating-pressure systems use a pump and cells, cost more and need servicing.
Decision
Risk assessment by clinicians decides which surface is used. Procurement supplies the surfaces specified. Sleepwit supplies foam surfaces and overlays, not powered systems.
What this means for buyers
Match the surface to the risk group set by clinicians, check bed compatibility and servicing for powered systems, and compare whole-life cost, including pumps, cells and maintenance. For many wards a well-specified foam mattress is the base surface, with powered systems reserved for higher-risk patients.
Comparison for procurement
| Factor | High-specification foam | Alternating-pressure system |
|---|---|---|
| Power | None | Pump and mains supply |
| Maintenance | Inspect and replace | Servicing, cells and pump |
| Upfront cost | Lower | Higher |
| Suitable for | Many at-risk adults | Higher-risk patients, as clinicians decide |
| Noise | None | Pump noise |
Detailed guidance
The two options solve different problems and are chosen by clinicians according to risk. A high-specification foam mattress is a passive surface: it redistributes pressure through its structure and needs no power. An alternating-pressure system actively changes where pressure falls using air cells and a pump, and may suit higher-risk patients or those who cannot be repositioned often.
From a procurement view, foam has lower upfront cost and little maintenance but must be inspected and replaced when it bottoms out. Powered systems need servicing, spare cells and staff training, and add noise and power requirements. Whichever you buy, specify the cover, fit and fire performance, and keep a register of age and condition. Do not buy on price alone: evidence for one surface type over another depends on the population and the comparison.
Worked example (illustrative figures)
A hospital assesses 100 beds. The clinical team decides that most patients are suited to a high-specification foam surface and a smaller group needs powered systems. Procurement buys foam mattresses for the first group and rents or buys powered systems for the second. Costs are tracked separately, because maintenance and servicing apply only to the powered units.
Frequently asked questions
Do you supply alternating-pressure systems?
No. We supply foam mattresses and overlays; powered systems come from specialist suppliers.
