Description
The Domus 4 Edge is a powered alternating pressure and low air loss mattress with 3 in (8 cm) firm foam transfer edges, 8 in high and 79 in long, in 36 or 42 in widths, rated 450 lbs (204 kg).
What does it do and how does it work?
- The control unit runs a 10-minute alternating cycle, a constant low pressure static mode, max inflate and seat inflation for the Fowler position.
- Low air loss moves air across the surface for microclimate control.
- Three-inch wide firm foam transfer edges run along both sides.
- The fluid-resistant quilted cover zips off in one step.
- A CPR release valve, a visual and audible alarm, and an auto-lock after five minutes are built into the system.
Who is it for, and who should choose something else?
- A person at medium to high risk of pressure injuries, which is how 5 Minds describes the Domus 4 Edge; the care team decides.
- A 36 or 42 in wide deck; the 42 in width needs a bariatric deck.
- It is not the stock Domus 4: the Edge adds the three-inch foam transfer edges.
- Someone who needs a foam mattress without power should choose a foam surface instead.
Will it fit?
- Widths are 36 in (91 cm) or 42 in (107 cm); length is 79 in (201 cm); height is 8 in (20 cm).
- The 450 lbs (204 kg) rating is the mattress limit; the bed frame's own safe working load applies if it is lower.
- The foam edges are part of the mattress, not bed rails. Assess the transfer method and the gaps to any rails with the whole bed. Health Canada recommends gaps under 120 mm (4 3/4 in) within and under the rail, and under 60 mm (2 3/8 in) at the rail ends. See bed rails.
- A mattress that has touched skin cannot be returned, so measure first. See the return policy.
Using it day to day
- Set the mode and comfort level on the control unit; the panel locks itself after five minutes.
- The CPR release valve deflates the surface quickly in an emergency.
- In a power failure the powered therapy stops; follow the care team's outage plan.
- Unzip the top cover for cleaning and check the surface for tears at each linen change.
What does it work with, and what are its limits?
- It is a powered mattress: no therapy without power.
- The foam edges do not prevent falls or entrapment.
- The control unit and cover are part of the system; the bed frame and rails are separate.
How does it compare?
- Med-Aire Plus 14029DP: a 10 in defined-perimeter air surface.
- Atlas Hybrid: non-powered at baseline, with firm foam borders.
- Alternating pressure mattresses: the category.
Frequently asked questions
Is Domus 4 Edge the stock Domus 4?
No. The Edge has three-inch foam transfer edges and its own width codes; the stock Domus 4 does not.
Can the edges replace rails?
No. They are part of the mattress; the bed, any rails and the mattress are assessed together for gaps and transfers.
What widths are available?
36 or 42 in, both 79 in long and 8 in high, each with its own part number and a matching deck.
