Medline Ultrasorbs Advanced+ Premium Underpads feature a superabsorbent polymer core that wicks away and absorbs fluid to help protect patient's or resident's skin while controlling odors while a non-liquid, permeable backsheet protects underlying surfaces and helps keep them dry. Their soft materials provide protection against friction and sheer which helps keep the patient or resident comfortable, and these unique underpads have a 300 pound weight capacity for boosting and repositioning patients. Plus, air-permeable materials such as these are ideal for use on low air loss mattresses and specialty support surfaces.
