Custom Care® Convertible surfaces represent the next generation of
time-tested PressureGuard air therapy surfaces. In peer-reviewed studies, non-powered2
and powered3 PressureGuard surfaces outperformed traditional powered surfaces in wound
healing through Stage 4.

Custom Care Convertible mattresses feature the innovative Star Chamber system
engineered with air support cylinders that are constantly filled with air – whether or not
the surface is powered. Even in their non-powered state, the air cylinders’ head-to-foot
orientation provides greater air displacement and better weight distribution than typical
side-to-side cylinder configurations, and the cross-connected elasticized reservoirs absorb
peaks to mimic powered flotation.
