NEW ZONAL FEATURE - Zonal castellation’s deliver enhanced pressure redistribution to the scapula, sacrum and heel area. Patients considered to be at high risk of developing pressure ulcers require a pressure redistributing support surface. Foam support surfaces that feature zonal castellation’s provide optimum patient support where required. The zonal Permaflex Plus features high density foam side formers within the mattress to provide support when moving or transferring a patient. The mattress cover reduces the risk of infection with welded seams and a concealed zip. In addition, the mattress cover is multi-stretch and vapour permeable.
