Underpad Knowledge｜A Complete Guide for Better Care

Underpads (also called disposable underpads or waterproof bed pads) are widely used in hospitals, nursing homes, and home care. They help keep beds and chairs clean while ensuring comfort and hygiene for patients. Here’s everything you need to know about underpads—their materials, how they work, benefits, and correct usage.

What Are Underpads Made Of?

An underpad is typically made of three layers:

• Top Layer: Soft non-woven fabric, skin-friendly and breathable.

• Middle Layer: Fluff pulp mixed with super absorbent polymer (SAP) for strong absorption and liquid retention.

• Bottom Layer: Durable PE waterproof film that prevents leakage and protects mattresses or chairs.
