The Mattress Cradle (NCL-CRD) provides raised side supports that fill the lateral gap between the mattress and bed side rails, holding the mattress centred and addressing the limb entrapment risk created when air mattresses are narrower than the bed frame. Suitable for static and dynamic air mattresses on profiling beds. MHRA entrapment zone management.

MHRA guidance on bed rail safety identifies lateral gaps between the mattress and bed rail as entrapment risk zones; for residents using active air mattresses that are narrower than the bed frame when inflated, this gap can be significant. The mattress cradle directly addresses this zone. CQC Regulation 12 (safe care) documentation should include the cradle as a component of the bed safety risk management plan where lateral gap entrapment has been identified. The tissue viability nurse should also confirm that the cradle does not affect the air mattress inflation cycle or pressure redistribution performance, as some cradle designs may constrain lateral mattress expansion.
Why do active air mattresses create a side gap when inflated?
Alternating pressure air mattresses are designed to fit within bed frames, but when their air cells inflate to their maximum pressure, the mattress width may not fully span the bed frame width. This can leave a gap of several centimetres between the inflated mattress edge and the bed side rail. The gap varies with the mattress specification, the bed frame width, and the inflation pressure setting; for heavier residents where higher inflation pressures are used, the gap may be more pronounced. The mattress cradle fills this residual gap, maintaining a safe lateral clearance regardless of the inflation state of the air system.
How does the cradle differ from the mattress side filler (NCL-MSF)?
The mattress cradle (NCL-CRD) is a single unit that holds the mattress centred within the bed frame using raised side supports along both sides simultaneously, providing a structural cradle around the mattress; it is primarily designed for use with active air mattresses where the mattress width varies with the inflation cycle. The mattress side filler (NCL-MSF) is a custom-sized foam filler that fills a static gap between the mattress edge and a specific rail or frame position on one side; it is more appropriate for fixed-width gap-filling requirements where a precise-fit custom filler is required rather than a bilateral structural cradle.
