A simple, affordable solution to maintaining skin integrity

Therarest® MRS, for patients who are at low risk for skin breakdown, offers two options designed to help prevent pressure injuries, provide patient comfort, and help facilities control costs.

Therarest® Perimeter Plus MRS and Therarest® Perimeter Plus VE MRS provide the same features, but they contain different foam material in the top layer underneath the cover.

A highly advanced visco-elastic foam mattress, the Therarest Perimeter Plus VE range combines the standard features of the Perimeter Plus mattress with a visco-elastic topper and a non-skid bottom, making it a high perfornance, cost effective mattress.

  • Visco-elastic memory foam molds to the resident's/patient’s body shape, providing a customised fit each time the resident/patient changes position, helping improve comfort and pressure redistribution.
  • Compression channels cut into the foam under anatomic zones help protect against pressure and shearing.
  • Sloped heel section helps prevent skin breakdown by transferring weight off the heel area.
  • Firm perimeter on each side provides support for residents/patients during ingress/egress and for caregivers during bedside assessments.
  • The TheraTex nylon mattress cover offers low Moisture Vapor Transmission (MVT) to help keep skin cool and dry.
  • Raised side bolsters (optional) serve as a passive reminder of the edge of the mattress and facilitate resident/patient ingress/egress.
  • Customisable length and width (optional) helps ensure a proper fit on a wide variety of bed frames.

    A pressure redistribution mattress that offers comfort and early intervention and treatment of pressure injuries for low-risk patients.
