Ending the pressure injury cycle for wheelchair users.

Aegis is a wheelchair cushion built to catch pressure injury risk before it starts — a continuous layer of protection where today there's only guesswork and scheduled checks.

Lifetime risk
70%

of wheelchair users will develop at least one serious pressure ulcer in their lifetime.

Protocol gap
66%

non-compliance with manual repositioning protocols — the current standard of care doesn't hold up.

Cost of inaction
60,000

deaths a year are linked to pressure ulcers that went undetected too long.

01 — why it happens

A problem that repeats because no one is watching continuously.

01

Sustained pressure

Prolonged loading on bony prominences cuts off blood supply to deep tissue for hours at a time.

02

Microclimate failure

Heat and moisture build up underneath — a 1°C rise in skin temperature can raise local tissue demand by around 10%.

03

Invisible damage

Deep tissue damage starts hours before anything is visible on the skin, which is usually too late to act.

Prevention today still depends on caregiver-assisted repositioning every two hours — unsustainable, and easy to miss.

It's a widespread problem, too: over 18M wheelchair users across Europe, with pressure ulcers costing an average of €10K per case each year.

02 — how it works

One cushion, doing three jobs at once.

Prevention

Continuous protection built into daily life, not scheduled checks.

Detection

Flags risk while it's still forming, hours before it's visible.

Action

Responds on its own — no waiting on a caregiver to notice.

03 — under the surface

Five layers, one system.

01 · Outer layer
What you feel against you.
02 · Sensing layer
Reads what's happening beneath the surface.
03 · Distribution array
Reshapes support, point by point.
04 · Conditioning layer
Regulates the layer above.
05 · Control base
Where it all comes together.
