Alerta Sensaflex Foam Mattress Underlay

When using a pressure relief mattress overlay, a supportive layer must be used underneath to provide support and pressure relief in the event of a power failure or air mattress deflation. The Alerta Sensaflex Foam Mattress Underlay is an ideal solution, made with 5cm of soft and comfortable foam to support your pressure relief mattress overlay system.

Who Needs the Alerta Sensaflex Foam Underlay?

 Mattress underlays are a crucial part of any pressure relief system that involves a mattress overlay – especially in the case of air mattress overlays. When using a mattress overlay like the Alerta Emerald Overlay Alternating Mattress System, a mattress underlay like the Alerta Sensaflex can prevent the patient 'bottoming out' in the event of a power failure, and ensure a level of pressure relief can still be provided in the event of deflation.

Is This Product Tested for Fire Safety?

Yes, all components of Alerta's pressure relief products are tested to comply with BS7177: Crib 5 fire safety regulations. This means that all foam, air cells and covers for Alerta mattresses and cushions are tested to the most stringent fire safety guidelines, ensuring you stay fully compliant and up to date with regulations.

Multi-Stretch, Water Resistant Cover

To improve durability and quality of care, this underlay mattress is fitted with a multi-stretch and waterproof cover. This vapour permeable PU cover is antimicrobial, to reduce bacteria and odour, and fully machine-washable so that you can keep your patient's environment sanitary at all times. 

Can the Cover Be Washed?

Yes, the cover can be machine washed at 65°C for no less than 10 minutes, or 95°C for no less than 3 minutes. The cover can then be tumble dried on low heat (not exceeding 60°C).
