Washable Underpads are reusable pads that are designed to protect
mattresses, chairs, and other surfaces from urine, sweat, and other
bodily fluids. They are made from absorbent materials such as cotton,
polyester, or a combination of both, and have a waterproof backing to
prevent leaks.
Washable underpads come in a variety of sizes and absorbency levels, and
can be washed and dried in a standard washing machine and dryer. They
are a cost-effective and environmentally friendly alternative to
disposable underpads, and are ideal for individuals with incontinence
issues, bedridden patients, and those who are recovering from surgery or
illness.
Some washable underpads also feature antimicrobial properties to prevent
the growth of bacteria and odors, and others have non-slip backing to
keep them securely in place. They are easy to use and maintain, and can
provide peace of mind and comfort for both patients and caregivers.
